Jump to line keyboard shortcut

[guarin]

Description

The keyboard shortcut for the "jump to line" command overwrites one of the keys I use but I cannot find the location where to disable to command/shortcut. I am talking about the command that opens the following window:

It is not listed in Settings -> Keyboard Shortcuts -> Default Settings and I did not add/overwrite it in the User Settings.

Reproduce

On my keyboard: Alt G

Overwriting the Setting does not solve the problem. Does anybody know a workaround?

[jasongrout]

This comes from the CodeMirror jump-to-line extension we load: https://github.com/codemirror/CodeMirror/blob/b9e6190b3edf16fe959055c45807e06f833f9d1f/addon/search/jump-to-line.js#L52

I don't have a keyboard where Alt G prints a key, but a workaround might be to define a keyboard shortcut in Settings>Advanced Settings>Keyboard Shortcuts that explicitly prints @ into the editor when you press Alt G:

{
  shortcuts: [
    {
      command: 'apputils:run-first-enabled',
      selector: 'body',
      keys: [
        'Alt G',
      ],
      args: {
        commands: [
          'console:replace-selection',
          'fileeditor:replace-selection',
          'notebook:replace-selection',
        ],
        args: {
          text: '@',
        },
      },
    },
  ],
}

[fabianegli]

@jasongrout Thank you, that works. I wonder if this could be a checkbox somewhere in the settings for users on macOS?

[jasongrout]

I think it is not about macOS, but about keyboard layouts in general. One problem here is that some editor keyboard shortcuts do not use the jlab keyboard shortcut system (like this Alt G). Instead, I think we should reimplement these keyboard shortcuts using the jlab keyboard shortcut system if possible. That would make it easy to customize the shortcut.

I don't have a keyboard where Alt G prints a key, but a workaround might be to define a keyboard shortcut in Settings>Advanced Settings>Keyboard Shortcuts that explicitly prints @ into the editor when you press Alt G:

Note that this workaround will most likely not work if Alt/AltGr + G is a dead key, which is for instance the case for the ergonomic bepo layout, where it is used to switch to the greek layer (which is surprisingly useful in Unicode-friendly languages like Julia, since it is faster than typing "\alpha" then TAB).

Right, we were trying to solve the problem of Alt+G being the combination to type @.

Or are you saying that in JupyterLab, instead of switching to the greek layer, Alt/AltGr + G is triggering the go to line functionality in CodeMirror?

[JLTastet]

Or are you saying that in JupyterLab, instead of switching to the greek layer, Alt/AltGr + G is triggering the go to line functionality in CodeMirror?

Yes, this is what I meant: with my keyboard layout, the "go to line" shortcut from CodeMirror is conflicting with a dead key and prevents access to an entire layer. In principle, I could use your workaround to explicitly redefine all the AltGr/Opt + g + [a-zA-Z], but that would be cumbersome.

Sorry if I wasn’t clear.

This issue has been mentioned on Jupyter Community Forum. There might be relevant details there:

[stepelu]

Hi, has there been any progress on this issue?
I can confirm that it is a pain point, for example I am using this math keyboard
https://www.cs.cornell.edu/andru/release/lattice-kbd/
where all the greeks are mapped via the alt-g dead key...

[JLTastet]

In Jupyter Lab 3.4.5 and 3.5.0 I still encounter this issue, but only with Firefox (106.0.5). I have no problem with Brave (1.45.123) or Safari (16.1). I am on macOS 12.6.1 (ARM).
