Equation Toolbar Hidden - Cannot Restore via Double-Click or Menu

Hello everyone,

I’m using ONLYOFFICE Desktop Editors v9.2.1 on macOS and have run into a persistent issue with the equation editor.

The Problem:
I accidentally clicked the “Hide Equation Toolbar” option (introduced in v7.5) while editing an existing equation. Now the dedicated toolbar for symbols, fractions, etc., is gone and I cannot get it to reappear to continue editing that specific equation. I searched the forums and release notes and see that the “Hide Equation Toolbar” feature was added in v7.5. A post from Feb 2023 also mentions that the “new equation toolbar… usually covers the equation from the line above,” indicating a UI/behavior change around that time. This suggests the method to restore it might differ from older versions or common expectations.

Core Question:
In the current interface (v9.2.1), what is the correct method to restore the Equation Toolbar for an already-inserted equation after it has been hidden? Is it a specific shortcut, a hidden toggle in a settings panel, or a known issue?

Any guidance would be greatly appreciated. For now, my workaround is to create a new equation and rewrite the old one, which is not ideal.

Thank you.

Hey @Sirius, :wave:

Thanks for the detailed report!

I don’t use the equation editor very often myself, so could you please record a short video showing the current state?
It would really help me (and the team) see exactly what happens when you try to edit an existing equation and how the toolbar is missing.

Just upload it to ONLYOFFICE DocSpace, kDrive, Google Drive or similar and share the link here.
No need for fancy editing — even a quick screen recording is perfect. (or attach here)

Appreciate your help — this will speed things up a lot!
