Agor y Golygydd Gweledol

I ddefnyddio'r Golygydd Gweledol wrth olygu, dewiswch "Golygu" ar y tab ar frig y dudalen. Gall agor y dudalen i'w golygu gymryd ychydig eiliadau, neu ragor os yw'r erthygl yn un hir. Dewiswch "Golygu cod y dudalen" i agor y golygydd gwreiddiol sy'n gallu golygu'r gystrawen wici yn uniongyrchol.
Gallwch agor y Golygydd Gweledol drwy ddewis y botwm "golygu" sydd i'w weld uwchben pob adran o'r erthygl, hefyd.

Bwrw iddi: bar offer y Golygydd Gweledol

Mae'r bar golygu yn ymddangos ar frig y dudalen pan rydych yn cychwyn ar y gwaith o olygu gyda'r Golygydd Gweladwy. Mae'n cynnwys nifer o'r botymau arferol.
	Gallwch Dad-wneud ac Ail-wneud eich darpar newidiadau.
	Mae "Penawdau" o'r fwydlen lithro yn caniatau i chi newid lefel y pennawd. Y lefel "Pennawd" sydd yn arfer cael ei roi ar benawdau adrannau. The normal format for text is "Paragraff".
	Formatting: Pressing the "A" opens a menu. The "Trwm" item (B) bolds the selected text. The "Italig" item (I) italicizes the selected text. The "Uwchysgrif" item (x2) causes the selected text to appear smaller than surrounding text and to be slightly higher than the surrounding text. The "Isysgrif" item (x2) causes the selected text to appear smaller than surrounding text and to be slightly lower than the surrounding text. The "Llinell drwodd" item (S) adds a solid bar through the selected text. The "Cod cyfrifiadurol" item (a set of curly brackets: {}) changes the font of the selected text to a monospaced font, which sets it apart from surrounding (proportionally spaced) text. The "Tanlinellu" item (U) adds a solid line beneath the selected text. The "Iaith" item (文A) allows you to label the language (for example, Japanese) and direction (for example, right-to-left) of the selected text. The final item (), called "Clirio", removes all character formatting from the selected text, including links. If you have not selected any text, then when you press the "A" to open the menu, and then select an item, that formatting will apply to the text that you start typing, from wherever your cursor is located.
	Linking tool: The chain icon is the linking tool. Pressing on it (usually after selecting some text) opens the link dialog.
	Cyfeirio menu: The "Cyfeirio" menu is used to add inline citations (also called "footnotes" or "references"). All projects have access to basic reference formatting and the ability to reuse citations by using this menu. It also gives users quick access to local citation templates, if these are enabled on their wiki. (Instructions for adding local citation templates to the Cyfeirio menu at a specific wiki are available at GolygyddGweladwy/Teclun cyfeiriadau .)
	botwm ⧼citoid-citefromidtool-title⧽: If the citoid service is enabled on your wiki, then you will see a ⧼citoid-citefromidtool-title⧽ button instead of a Cyfeirio menu. The citoid service tries to fill out citation templates automatically.
	Rhestri & chilosod: Mae'r ddau eicon cyntaf yn caniatau i chi greu rhestri wedi'i rhifo neu restri o fwledi. Mae'r ddau eicon olaf yn cynyddu neu'n lleihau maint y cilosod.
	Cyfryngau, cyfeiriadau & trawsgynnwys: Rhoddir deilaog parod ar eich cyfer: Mae'r eicon "Ffeil gyfrwng" (llun mynydd) yn agor dialog y cyfryngau (delwedd, sain ayb). The "Templed" icon (a puzzle piece) allows you to edit templates. The "Table" item allows you to insert a table. The "Sylw" item (a speech balloon) allows you to insert comments that are not visible to readers; these comments can be seen only when in edit mode, where they are indicated by an exclamation mark icon. In edit mode, pressing on the exclamation mark icon allows you to edit or delete the comment. The "Hieroglyffigau" icon (an ankh symbol - ☥) allows you to enter the hieroglyphics inserter. (See below.) The "Code block" item allows you to insert code. The "Musical notation" item allows you to insert a musical notation. The "Oriel" icon (a set of photos) allows you to insert a gallery to the page. The "Math formula" icon (Σ) opens the formula inserter dialog. The "Graph" item allows you to insert a graph. The "Your signature" item allows you to insert a signature that you use on the project. It will be greyed out (not selectable) when you are editing a type of page (a "namespace"), such as an article, where signatures should not be inserted. Mae'r eicon "Rhestr cyfeiriadau" (tri llyfr) yn agor dialog i ddangos y cyfeiriadau.
Special character insertion: The "Nodau arbennig" (Ω) icon is next to the "Mewnosod" menu. When pressed, it displays a dialog showing many special characters. By pressing on a specific character, you place it into the text. These special characters include some standard symbols, diacritics, and mathematical symbols. (This list may be customized locally. See VisualEditor/Special characters for instructions.)

	The Edit notices button displays any notices for the page.
	"Dewisiadau tudalen" eich golygiadau. Categorïau allows you to add categories to this page and to adjust how the page is sorted, when displayed within a category by setting a different index to sort with. Gosodiadau'r dudalen allows you to make the page a redirect and adjust options of this redirect, to adjust settings regarding the displaying of the Table of Contents, to disable the edit links next to each heading, and to define the page as a disambiguation page. Advanced settings allows you to adjust the settings regarding indexation of the page by search engines, showing a tab to add a new section, and the displayed title. Languages which shows a list of pages in other languages that are linked to that page. Templates used shows a list of links to each template used on this page. The tabs of the Options dialog are also displayed in the Dewisiadau tudalen menu and can be opened by clicking on it. Furthermore the Dewisiadau tudalen menu contains the button View as right-to-left and the button Find and replace which opens a dialog where you can insert characters, terms or Regular expressions you are searching for and those to replace them with, together with several buttons for options.
	The switch to source editing button is next to the Cyhoeddi newidiadau button. It allows you to switch to the wikitext editor.

Cadw eich golygiadau

Wedi i chi orffen golygu dewiswch y botwm gwyrdd "Cyhoeddi newidiadau" yn y bar offer. Ni ellir dewis y botwm gwyrdd hyd nes i chi wneud rhyw newid i'r dudalen. To cancel all your editing changes, close your browser window, or press the "Darllen" tab above the edit toolbar.
Mae dewis y botwm gwyrdd "Cyhoeddi newidiadau" yn agor dialog bychan; gallwch fewnosod crynodeb byr o'r hyn a wnaethoch, gallwch hefyd nodi mai golygiad bychan ydoedd, a medrwch ddewis cadw golwg ar olygiadau'r dudalen hon yn y dyfodol. Mae'r rhif hwn yn nodi faint o le gwag sydd gennych yn eich crynodeb golygu. Gallwch hefyd adolygu eich newidiadau, er mwyn cadarnhau eu bônt yn gweithio'n iawn - cyn cadw'r dudalen. The "Parhau i olygu" button returns you to the page you were editing. You can publish all of your changes later.

Golygu cysylltau

	Gallwch ddewis dolen drwy'r eicon "Dolen", a welir yn y fwydlen, neu drwy ddefnyddio Ctrl+K (neu ⌘ Command+K ar gyfrifiadur Mac). Os dewiswch dalp o destun neu roi eich cyrchwr ar air, bydd pwyso "Dolen" yn mewnosod dolen ar y testun hwnnw.
	Gallwch gyrraedd y dialog cysylltu drwy'r botwm neu'r llwybr byr. Yno, gallwch deipio'r cyswllt. Os mai cyswllt mewnol (sef cyswllt i dudalennau eraill yn Wicipedia) sydd gennych, bydd y Golygydd Gweledol yn ceisio eich cynorthwyo drwy gynnig enwau tudalennau tebyg i'r hyn sy'n cael ei deipio. The link tool will try to help with internal links by searching for likely matches.
	Unwaith i chi deipio'r cyswllt neu ei dewis, gallwch bwyso ar ↵ Enter, neu glicio tu allan i'r blwch, neu bwyso'r eicon cau (<). Bydd eich cyswllt yn ymddangos ar y dudalen sydd ar waith gennych yn y Golygydd Gweledol, ond ni chaiff ei roi ar gadw hyd nes i chi gadw'r dudalen gyfan.
	I gysylltu â thudalen we tu allan i Wicipedia, yr un yw'r broses. Teipiwch y cyswllt yn y maes ac fe gaiff ei ychwanegu yn "gyswllt allanol".
	External links without labels look like this: [1]. You can add these by placing your cursor away from any word (e.g., after a space). Open the link tool by pressing on the button or pressing the shortcut keys. Type the URL in the box, and press the "Wedi cwblhau" button to insert the link.
	I addasu neu ddiddymu dolen, cliciwch y ddolen, yna dewisiwch yr eicon "Dolen" gerllaw. Gallwch hefyd ddewis yr un eicon yn y fwydlen neu ddefnyddio Ctrl+K ar eich bysell. When a link is selected, it appears as blue framed. Yna, medrwch olygu targed eich dolen, neu ei diddymu'n gyfangwbwl drwy bwyso'r eicon "Tynnu'r fformatio" (bin sbwriel) yng nghornel dde uchaf y dialog. You can also open the link's target in another window by pressing on the copy of the link in the dialog box. (You might want do this to check if an external link is valid.) If you want to exit the link label (the text displayed as a link) or continue to write after this link, you can press →: Pressing it once will escape the link editing dialog and put your cursor at the end of the element linked (blue framed, to edit this element) Pressing it twice will put the cursor after the element linked, ready to type the rest of your text. To edit the link label of an existing link, press within the link label and type the new one. But if you want to replace the entire label, please note: If you have selected (highlighted) the entire link label, the link will be deleted by typing any key. You may link it from start. To keep the link directly, you may press within that link label, use backspace and delete key without pressing it once more than necessary, and a narrow blue link area will remain there. Now you may type in the new label for the kept link. You can also link to categories, files and more.

Determining which system is in place
Your wiki may use one of three footnote systems. The one shown on the right is the simplest system, where the "Cyfeirio" menu does not include any citation templates. If your wiki uses this system, then everything you need to know about footnotes is on this page.
The second system has the same type of "Cyfeirio" menu, but with several popular citation templates set up for quick access. If your wiki uses this system, then you will find more details at Help:VisualEditor/User guide/Citations-Templates
In the third system, you again start by pressing the Cite button. Then a dialog box opens, which includes an automatic citation process using the citoid service. If your wiki uses this system, you will find more details at Help:VisualEditor/User guide/Citations-Full
Golygu cyfeiriad
I olygu cyfeiriad sydd eisoes ar gael, cliciwch ar y cyfeiriad yn y testun. Yna cliciwch ar yr eicon "Cyfeirnoderence" (llun llyfrnod) sy'n ymddangos gerllaw, neu'r eicon yn y bar offer.
Mae dewis yr eicon "Cyfeirnoderence" yn agor dialog sy'n cynnwys golygydd pitw, ble y medrwch olygu testun y cyfeiriad. Mae nifer o wicis yn defnyddio nodiadau i fformadu cyfeiriadau yn ôl patrwm arbennig. Mi wnewch chi sylwi ar hyn wrth i chi olygu cyfeiriad sy'n troi yn las pan 'da chi'n ei ddewis. If a template was used and you press on the reference information, then the Templed icon (puzzle piece) will appear with some information. Press on the "edit" button to edit the content of the template in the template mini-editor dialog.
If what appears when you press on a reference is an icon for a standard template for citations (an example is at right), then pressing "Edit" will open the template mini-editor dialog.
O glicio ar yr eicon Trawsgynnwys (y darn jigso) gallwch olygu paramedrau'r nodyn.
Cliciwch ar "Gweithredu'r newidiadau" pan fyddwch yn barod, ac fe ewch yn ôl i'r golygydd cyfeiriadau.
Ailddefnyddio cyfeiriad
Os oes cyfeiriadau ar y dudalen eisoes, gallwch ailddefnyddio un ohonynt os yw hefyd yn ffynhonnell i ddarn newydd o'r testun. I ailddefnyddio cyfeiriad, gosodwch eich cyrchwr yn y man lle caiff ei ychwanegu. Yna cliciwch ar yr eicon "Cyfeiriad" (llun llyfrnod) yn y bar offer. (Note: If your wiki has the third footnote system described above, you'll see a "Re-use" tab, in a dialog, instead of a "Re-use" item on the "Cyfeirio" menu.)
Os oes llawer o gyfeiriadau i gael, gallwch ddefnyddio'r bar chwilio (a'r label "At beth ydych chi am gyfeirio?" arno) i ddangos dim ond y cyfeiriadau sy'n cyfateb i ryw destun benodol. Chwiliwch y rhestr am y cyfeiriad sydd arnoch eisiau ei ailddefnyddio, a'i ddewis.
Ychwanegu cyfeiriad newydd
I ychwanegu cyfeiriad newydd, rhowch eich cyrchwr yn y man lle caiff ei ychwanegu. Yna cliciwch ar yr eicon "Cyfeirnod" (llun llyfrnod) yn y bar offer.
Using the "Basic" citation
Shown here is what you will see if you select the basic references item. Gwaith y golygydd cyfeiriadau yw ychwanegu ffynhonnell, ei golygu a'i fformatio. Gallwch ychwanegu'r cyfeiriad at ryw grŵp o gyfeiriadau. Mae grŵp o gyfeiriadau yn cael eu dangos gyda'i gilydd drwy ddefnyddio'r teclyn "Rhestru cyfeiriadau".
Os ydych yn ychwanegu cyfeiriad newydd ac am ddefnyddio nodyn ynddo, cliciwch yr eicon Trawsgynnwys (darn jigso) ym mar offer y golygydd cyfeiriadau.
Yna, chwiliwch am y nodyn pwrpasol, ychwanegwch ef a'i olygu yn ôl eich gofyn. O orffen golygu'r nodyn, cliciwch ar "Gweithreder y newidiadau" i ddychwelyd at y golygydd cyfeiriadau, a chlicio ar "Gweithreder y newidiadau" yn fanno i ddychwelyd i'r dudalen sydd ar y gweill.
Os nad oes rhestr o gyfeiriadau ar y dudalen yn barod (e.e. os ydych wrthi'n ychwanegu'r cyfeiriad cyntaf ar y dudalen), yna mae angen ychwanegu hwn er mwyn i destun eich cyfeiriad gael ei ddangos. Rhowch y cyrchwr yn y man yr ydych am ddangos y cyfeiriadau (ar waelod y dudalen fel arfer), a chliciwch yr eicon "Rhestr cyfeiriadau" (tri llyfr).
Os wnaethoch osod cyfeiriadau mewn grwpiau, gallwch osod enw rhyw grŵp yn y dialog, a chaiff y cyfeiriadau sy'n perthyn i'r grŵp hwnnw eu dangos. I ychwanegu rhestr cyfeiriadau, cliciwch ar "Gweithreder y newidiadau" ar y dialog.
Using standard cite templates
Your local wiki may have added extra citation templates to the "Cyfeirio" menu. If so, you have quick access to the most-used citation templates for your wiki. (Instructions for adding extra citation templates to your local wiki are available at GolygyddGweladwy/Teclun cyfeiriadau .)
Pressing on a template icon such as "Cite book" will take you into the template mini-editor for that template. Important information fields may be marked with an asterisk. While the most common fields will be shown, not all of them are required.
To add more parameters, scroll down in the template mini-editor and press on the "Ychwanegu gwybodaeth ychwanegol" option. Press on "Mewnosod" when you are done.

Editing images and other media files

Editing images
I ychwanegu delwedd newydd (neu gyfryngau eraill) i'r dudalen, dewisiwch "Cyfryngau" yn y fwydlen (llun mynydd).
Mae dewis "Cyfryngau" yn agor dialog sy'n chwilio'n otomatig drwy Gomin Wikimedia am ffeiliau cyfrwng sy'n berthnasol i'r dudalen rydych yn ei golygu. Gallwch chwilio am gyfryngau eraill drwy newid y testun ym mlwch dialog y chwiliad. Cliciwch ar fân-lun (bawd) i ddewis ffeil. This places the image onto the page you are editing.
Mae'r dialog ar gyfer cyfryngau'n caniatau i chi ychwanegu testun, a all gynnwys fformat arbennig neu ddolenni.
The media dialog also allows you to add alternative text captions, to help users who use screen readers, or who have disabled image display.
You can also set various parameters for the image in the "Gosodiadau Uwch" window. These include the alignment, the type, and size of the image.
Wedi i chi gwblhau eich gwaith, dewiswch "Gweithreder y newidiadau" i gau'r dialog a dychwelyd i'r golygydd.
For an existing image, you can add or edit a caption or other settings by pressing on the image, then pressing on the "Ffeil gyfrwng" icon that appears below the picture. You can resize an existing image by pressing on it, then moving the resize icon (the two-headed arrow on one or both bottom corners). You can also drag and drop an image to a place higher or lower on the page.

Uploading images

You can upload images from a tab in the media dialog, or by dragging and dropping a file into the editor, or by pasting an image from your clipboard.
Press the "Upload" tab and select an image from your computer. You can type the file name, or drag an image into the box. If you dragged and dropped an image directly into the editor, or pasted one from your clipboard, this tab will open automatically.
You need to describe the image and add categories to it so that other people can find it.
The image will be inserted into the page when you are done.

Editing media galleries

To add a new gallery, press the "Oriel" icon (a set of photos) on the "Mewnosod" menu. (If you don't see this icon on that menu, then your local wiki has decided to delay implementing this functionality in the visual editor.)
To edit an existing gallery in the visual editor, press that gallery. Then, near the bottom of the gallery, press the gallery icon (a set of photos). This brings up the gallery editor, with the full list of images included in the gallery.
The gallery editor is currently a simple box that allows you to edit existing galleries using wikitext markup. To add a new image to an existing gallery, type the file name, followed by a bar (|) and the caption for that image. You must put each image in the gallery on its own line. You can also edit this list to remove or rearrange images or to change captions. When you press the "Wedi cwblhau" button, you will exit the gallery editor. You should then see your changes, with the gallery as it will now appear to readers. Remember that exiting the gallery editor does not publish your changes. As with other changes made using the visual editor, you must publish the entire page in order to publish your work.

Editing templates

Starting

I ychwanegu nodyn newydd, rhowch eich cyrchwr yn y man lle caiff ei ychwanegu. Yna cliciwch ar yr eicon "Trawsgynnwys" (llun darn jigso) yn y bar offer.
Rhowch enw'r nodyn sydd i'w osod, a chliciwch "Ychwanegu nodyn".
Gallwch hefyd olygu nodyn sydd ar y dudalen eisoes, wrth ei ddewis (bydd yn troi'n las ei liw), yna clicio ar yr eicon "Trawsgynnwys" (darn jigso) a ymddengys, neu'r eicon yn y bar offer.
Some templates are not visible to someone reading a page. In the visual editor, such hidden templates are shown as puzzle icons. The name of the template will be shown next to the puzzle icon.
When you select the icon, the context menu is displayed, and you can edit the template.
Template parameters
When you add a new template or open an existing one, the "Cynhwysiad" dialog is shown. The contents depends upon whether the template has been documented using the new TemplateData system or not.
The template shown here has no TemplateData set up for it. The dialog therefore provides a link to documentation for the template. By visiting the documentation you should be able to figure out if the template has any parameters (fields), and what goes in each field. Use numbers as the name for each nameless parameter. The first un-named parameter is named 1, the second is named 2, and so forth.
If a template has been updated to contain TemplateData information, then the dialog will show a list of individual (named) parameters.
Gallwch ychwanegu paramedrau neu olygu'r rhai a restrwyd eisoes.
Pan fod nodyn yn cael ei gynnwys mewn nodyn arall, fe fydd yr is-nodyn yn ymddangos fel paramedr yn y brif nodyn. Gallwch olygu'r is-nodiadau, neu cael eu gwared, drwy glicio ar enw'r is-nodyn. Gallwch ychwanegu is-nodiadau drwy ddilyn yr un camau ag wrth ychwanegu paramedr. Efallai y bydd yn rhaid edrych ar ddogfennaeth y nodyn er mwyn cadarnhau fod yr is-nodyn yn cael ei gynnal.
Cwbwlhau
Wedi i chi gwblhau'r Nodyn (template), dewiswch "Gweithredu'r newidiadau" i gau'r ddialog a dychwelyd i'r golygydd.
Substituting templates
When a template must be substituted, type subst: (colon included) before the template's name. Autocompletion doesn't work with subst:. If you want to use autocompletion, first find the template you are looking for, and then add subst: in front of the template name. Then, press the blue "Ychwanegu templed" button. Add any parameters as usual and press "Mewnosod".
You will see the template expand on the page after you press "Gweithredu'r newidiadau".

Editing lists

	You can use the visual editor to create lists, or to change the format of an existing list. There are two types of lists: unordered (bullet) and ordered (numbered). To start a new list, just press on one of the two menu items shown here. Or, if you already have typed the list (on separate lines), select (highlight) the list you have typed, then press on one of the menu items.
	Shown here are examples of the two types of lists: unordered (bullet) and ordered (numbered).
	If you want to change the indentation level of part of an existing list, select the part of the list that you want to change.
	Then use the menu, or press the Tab key. (The Tab key increases indentation; use the shift key plus the Tab key to decrease indentation)
	Here is the result of increased indentation.
	You can even mix ordered (numbered) and unordered (bullet) lists, if the list items have different indentations.

Editing tables

	You can use the visual editor to insert and change tables. You can even import a table by dragging a comma-separated value (.csv) file from your computer into the main editing window.
When you press on "Table", in the "Mewnosod" menu, the visual editor inserts a blank four-by-four table. Now the "Table" menu is available. From that menu, you can add a caption to the top of the table.
To select a cell, press it once.
To edit the contents of the cell (for example, to add content or to correct a spelling error), double press in the cell. Or you can select the cell and then press Return. To end your editing of a cell, just press elsewhere.
	You can add or delete a column or a row.
You can merge cells: Select them, then from the Table menu, press on "Merge cells".
If you merge cells, only the text in one cell is kept; any text in the other cells is deleted when you merge the cells. If you decide that you wanted some or all of the text that was deleted, use the Undo button, move or copy the text you want, then merge the cells again.
You can also split cells that were previously merged. All the content that was in the merged cell will remain in the first cell when you do the split. You can then cut and paste text to other cells, if you want.

Golygu categorïau

	To edit categories, on the "Dewisiadau tudalen" menu, press the "Categorïau" item.
	O glicio'r botwm "Options", bydd dialog yn agor sy'n rhestru'r categorïau sydd ar y dudalen eisoes, ac yn eich galluogi i ychwanegu rhai newydd. Yn "dewisiadau" gallwch osod yr enw (sef yr allweddair) y bydd y meddalwedd yn ei ddefnyddio'n ddiofyn wrth drefnu'r dudalen yn ôl yr wyddor ar y tudalennau categorïau. For example, the default sorting key for the article "George Washington" is "Washington, George". In the category "Presidents of the United States", the article is listed under the letter "W", not the letter "G".
	I ychwanegu categori newydd, rhowch yr enw yn y blwch "Ychwanegu categori". Gallwch osod categori newydd, neu ddewis categori sydd eisoes ar gael.
	I dynnu'r dudalen i ffwrdd o ryw gategori, cliciwch arno, a bydd dialog yn agor. Yna cliciwch ar yr eicon "Tynnu i ffwrdd" (bin sbwriel) yn y dialog. Gallwch hefyd ddefnyddio'r dialog hwn i osod allweddair i'r categori hwn (i'w ddefnyddio wrth drefnu yn nhrefn yr wyddor) sy'n wahanol i'r un diofyn.
	Cliciwch ar "Gweithreder y newidiadau" pan fyddwch yn barod, ac fe ewch yn ôl i olygydd y dudalen.

Editing page settings

	To edit a page's settings, press to open the "Dewisiadau tudalen" menu, in the toolbar, and select the "Gosodiadau'r dudalen" button.
	The "Gosodiadau'r dudalen" button opens a dialog that shows several options.
	You can make a page a redirect to another page by checking the "Ailgyfeirio'r dudalen i" checkbox, and then typing the name of the page to which you want to send the reader who tries to go to the page that you are editing. At the bottom is the option to prevent page renames from updating this redirect. This is very rarely used.
	You can change whether the page shows a Table of Contents by selecting one of these three buttons. The default option is "Os oes angen", which shows a Table of Contents if there are three or more headings.
	You can make a page not show edit links next to each section header by checking this checkbox.
	Press "Gweithredu'r newidiadau" when you are done editing the Dewisiadau tudalen to return to the page editor.

Editing maps

You can add and change maps. See Help:VisualEditor/Maps .

Editing mathematical formulae

To add a new mathematical formula to the page, place your cursor where you want it to be inserted, and press on the "Math formula" icon ("Σ") in the "Mewnosod" menu on the toolbar.
A window will open in which you can type the formula, using LaTeX syntax. the visual editor will update the formula as you type it, so you can see how it will look as you make changes. Once you are happy with the formula, press the "Mewnosod" button.
To edit an existing mathematical formula on the page, press on it and then press on the "Σ" icon that appears. This will open up the formula window, where you make changes.
Mathematical formulae can be placed inline or centered as a block.

Editing musical scores

To add a new musical notation to a page, place your cursor where you want the musical notation to be inserted. Then, from the "Insert" menu on the toolbar, press the "Musical notation" option. To edit an existing musical notation on the page, double press on it.
This will open the "Musical notation" dialog. Here the notation can be edited by scale, either in ABC or in Lilypond format. You can also link the notation to an audio or MIDI file. Once you are finished, press the "Done" button to close the dialog and publish your changes.

Golygu fformwlâu mathemategol ac eitemau arbennig eraill

Nid yw'r Golygydd Gweledol yn cynnal rhai eitemau arbennig eto, megis orielau delweddau, fformwlâu mathemategol, papur erwydd a nodau diacritig. Hyd nes y bônt yn cael eu cynnal, bydd yn rhaid i chi olygu côd y dudalen, gan ddefnyddio cystrawen wici, er mwyn ychwanegu'r rhain neu eu golygu.
In most cases, the existing items can be edited, but new ones cannot be inserted in the visual editor. Until they are fully supported, you can copy an existing one from another page, or edit the source wikitext directly.

Switching between the visual and wikitext editors

To switch from the visual editor to the wikitext editor, press the [[ ]] button on the far right of the toolbar.
If you've done any editing, you'll be asked whether you want to keep your changes. Normally you'll press on "Keep changes".
You'll see a diff. (If you pressed on "Discard changes", you'll just see wikitext, ready to edit with the wikitext editor.) Scroll down, and you'll see the wikitext editing area.
You can also switch from the wikitext editor to the visual editor. To do that, press the pencil icon on the far right of the toolbar.
After you press the pencil icon, if you've done any editing you'll be asked whether you want to keep your changes. If you press "Keep changes", you'll go to the visual editor. If you press "Discard changes", you'll be asked to confirm that is what you want to do (press on "Leave Page" to confirm) before the visual editor will start.
