When hovering the cursor over the starting symbol of inline math mode, $, or over \begin{equation}, Texstudio gives a preview of the typeset math. I love this feature, but it only works in these two cases. Mostly I use \[ for math, or the align environment, so I would like to add my own environments to trigger this preview.

Someone else felt the same way and opened this ticket on Sourceforge, and it was closed as "implemented". But then how does one do it?

  • @Qrrbrbirlbel, I have 2.5.2, same as you. How do you add new triggers? – Jeremy Voltz Apr 12 '13 at 20:03
  • @JeremyVoltz I don't think I had to add any new triggers. In the configuration window is a section “Custom Highlighting” wher e you can specify new environments to be from type “Numbers”, though this section is empty, so I don’t think that has anything to do with it. It seems to only work when I hover over the \end{align} part, not the formula itself or the \begin{align} part. – Qrrbrbirlbel Apr 12 '13 at 20:13
  • @Qrrbrbirlbel, you're right, it works for the \end{align}. Does it work for you on \[? That seems to be a no go, which is what I most want it for. – Jeremy Voltz Apr 12 '13 at 20:27

    @JeremyVoltz Correction: It works on \begin and \end, not on align or the formula. No it does not work with [, but if you use amsmath anyway you can use the equivalent equation* environment instead. – Qrrbrbirlbel Apr 12 '13 at 20:40

TeXstudio provides preview images for math content inside of

  • $ … $ (while hovering over the first $) and
  • all amsmath environments while hovering over the \begin or the \end part. It won’t work when the mouse only hovers over the name of the environment or the formula itself.

It won’t work with the display-math \[ … \] syntax, but as this is only a short cut to the equation* environment when amsmath is loaded, you could replace the syntax\[ … \] with \begin{equation*} … \end{equation*} if you need the preview here as well.

The alignat environment produces a preview with misplaced sub-formula parts and (if activated) equation numbers.


The math recognition for tooltip preview will be improved in the next release. This includes hovering over \[ and over the environment name (e.g. align in \begin{align}). Furthermore there will be better detection of multi-line formulas.

  • Should this be implemented for align now? I am using 2.8.6 on Windows and it doesn't seem to work. Working fine for equation. – kennyB Nov 18 '14 at 0:06

    @kennyB: There was a bug preventing the tooltip for a number of environments. This will be fixed in the next release (>2.8.8). – Tim Hoffmann Dec 9 '14 at 20:54
