jupyterlab-desktop No "undo" on Mac in a notebook cell

Description

I can not find any key combination that perform an undo in a cell. For any kind of cell : python, markdown or raw.

I've tried crtl-z, cmd-z, ctrl-shift-zand cmd-shift-z. No success. It makes JupyterLab unusable :-(

Context

Operating System and version: Mac OSX 13.3.1 Ventura
JupyterLab-Desktop version: 3.6.2-1
Installer: .dmg

Thank's for your help

@mbektas Are there any other commands in JupyterLab Desktop that do what @oliviermarti describes?

@krassowski pointed out that https://github.com/jupyterlab/jupyterlab/issues/10791 provides info about applying "undo" and "redo" to individual cells' contents. Does this address your issue?

I've found information about this experimentalDisableDocumentWideUndoRedo option in StackOverFlow. I've tried to play with it but it doesn't change anything. It's an option about having an undo/redo local to a cell, or more global. It has no effect when undo/redo is not working at all.

PS : I've found the option in the json settings editor view, but not in the default view with click boxes .. (??)

I'm not sure this is exactly the same issue, but this is what happens on my Mac installation: CMD+Z and CTRL+Z look binded at higher level (Electron? This is not a standard Mac shortcut except for undo AFAIK). Typically, they will close the current tab when pressed.

I've had success rebinding undo to OPTION+Z (in Settings > Advanced settings editor > Keyboard Shortcuts), as there does not seem to be any other conflicting keybinding. @oliviermarti you might want to try that as a temporary solution.

@abulte I'm a bit puzzled with the advanced syntax editor :-( Could you give me the exact lines you add ? Thank in advance Olivier

I just click on "Add" on the shortcut I'm interested in, and then input my key combination (eg type OPTION+Z).

@oliviermarti I am not able to reproduce this issue. Cmd + Z works fine for me for undoing text input in cells.

@mbektas I can reproduce, maybe a Mac OS version or architecture (Silicon here) issue? I'm on a fresh Mac OS install so there should not be any funny stuff in my config.

I tried it on an Apple silicon as well and still cannot reproduce. Do other shortcuts such as Cmd + A (Select all) work for you?

Jun 07 '23 04:06 mbektas

Yes. Cmd+A, Cmd+C, Cmd+V, Cmd+X are ok.

Olivier

Yes. Cmd+A, Cmd+C, Cmd+V, Cmd+X are ok.

Did you find a solution to your problem ? I'm experiencing the same behavior on my MacBook Pro (M2)...

I'm presently using option-Z for cancel. Didn't find any proper solution :-(

Could you retry with the latest version v4.0.5-1? There wer some Electron.js updates which might also include a fix for this issue.

Sep 12 '23 15:09 mbektas

@mbektas still no luck here with this version

Same for me. I've tried to reset to settings to defaults. Olivier

Not working for me. So, on the same laptop Jupyter Lab "CMD-Z" is working fine". But not with Jupyterlab Desktop
