VisualEditor/Beta Features/Formulae

You can opt-in to a VisualEditor plug-in that lets you create and edit mathematical formulae as part of the Beta Features programme. This is to gather feedback from users ahead of making it available for all VisualEditor users, once it is more polished.

Please remember to always review your changes before saving when using experimental features.

Once opted-in, you will get a new item in the "More" section of the toolbar, currently labelled "Formulae" and showing a Sigma as its icon ("Σ"). Similarly, existing formulae will now get a Sigma icon when you select them.

Clicking the icon will pop up an inspector to insert a new formula or edit the existing one, which takes a LaTeX expression (like the existing ‎<math> system – for example, enter "e^{i\pi}" or "f(x)=3^x"), and updates the image of the formula.

If you have any feedback about editing formulae, please comment on the discussion page with your concerns, queries or suggestions.
