VScode rejects keyboard shortcut CTRL + ù – Ubuntu

I am working on OS Ubuntu 22.04 running inside a Virtualbox VM hosted in a windows 10 OS.

Inside the VM, it seems that my VScode has reset some of the user-defined keyboard shortcuts I have previously set.

So I want to re-define them.

I want to change the keyboard shortcut of "Toggle Line Comment", which is set from CTRL + Y to CTRL + ù ( currently CTRL + Y is assigned by the system to "redo", and that is OK ).

enter image description here

So I click on the pencil icon of "Toggle Line Comment",

press the keys combination CTRL + ù

enter image description here

"ù" gets interpreted as "[Backslash]"

press enter

but then I still see assigned CTRL + Y (as if the change was rejected); and from some tests I did, that one is the only combination that manages to toggle comment lines.

I have tryed to restart VScode but nothing changes, I cannot edit the settings from the UI.

So I have tryed to edit them from the keybindings.json

tommaso@tommaso-VirtualBox02:~$ sudo locate keybindings.json    
/home/tommaso/.config/Code/User/keybindings.json

tommaso@tommaso-VirtualBox02:~$ vim /home/tommaso/.config/Code/User/keybindings.json

And the content of the opened file is

[    
    {    
        "key": "ctrl+alt+[Backslash]",    
        "command": "editor.action.blockComment",    
        "when": "editorTextFocus && !editorReadonly"    
    },    
    {    
        "key": "ctrl+shift+a",    
        "command": "-editor.action.blockComment",    
        "when": "editorTextFocus && !editorReadonly"    
    },    
    {    
        "key": "ctrl+shift+7",    
        "command": "-editor.action.commentLine",    
        "when": "editorTextFocus && !editorReadonly"    
    },    
    {    
        "key": "ctrl+[Backslash]",    
        "command": "editor.action.commentLine"    
    }    
]

It is indeed strange that the last {} entry I have added via the UI is missing the "when" key.

Anyway I have edited the content to

[
    {
        "key": "ctrl+alt+[Backslash]",
        "command": "editor.action.blockComment",
        "when": "editorTextFocus && !editorReadonly"
    },
    {
        "key": "ctrl+shift+a",
        "command": "-editor.action.blockComment",
        "when": "editorTextFocus && !editorReadonly"
    },
    {
        "key": "ctrl+shift+7",
        "command": "-editor.action.commentLine",
        "when": "editorTextFocus && !editorReadonly"
    },
    {
        "key": "ctrl+[Backslash]",
        "command": "editor.action.commentLine",
        "when": "editorTextFocus && !editorReadonly"
    }
]

saved,

restarted VScode

but again, the "toggle line comment" gets activated only by CTRL + Y.

The strange thing is that the CTRL + ALT + ù, that is

    {
        "key": "ctrl+alt+[Backslash]",
        "command": "editor.action.blockComment",
        "when": "editorTextFocus && !editorReadonly"
    }

works fine.

It is like VS code cannot load changes from keybindings.json .

What can be blocking the edit?

    From another machine having the same key VScode shortcut configuration, and having the shotcuts properly working on VScode, I accessed the content of keybinding.json, and it is the following

    // Place your key bindings in this file to override the defaultsauto[]
[
    {
        "key": "ctrl+shift+[Backslash]",
        "command": "editor.action.blockComment",
        "when": "editorTextFocus && !editorReadonly"
    },
    {
        "key": "ctrl+shift+a",
        "command": "-editor.action.blockComment",
        "when": "editorTextFocus && !editorReadonly"
    },
    {
        "key": "ctrl+[Backslash]",
        "command": "editor.action.commentLine",
        "when": "editorTextFocus && !editorReadonly"
    },
    {
        "key": "ctrl+shift+7",
        "command": "-editor.action.commentLine",
        "when": "editorTextFocus && !editorReadonly"
    }
]

    It is exactly the same content of the one on the other machine, for which it was not working properly.

    So the problem is machine-related.

    So the end I have set the key combination ctrl+à for the toggle line comment, and it is OK.

    I think the problem is somehow linked to how VScode interprets a key:

    I have an italian keyboard having a key which contains "§" and "ù", but VS code somehow interprets it as "[Backslash]".

    Once again I want to underline that it is strange to me that

    1. ctrl+alt+ù

    is correctly got as change by VScode, while

    1. ctrl+ù

    is rejected ( the UI swithces the combination automatically to "ctrl"+"y", while on the keybindings.json it is actually written "ctrl+[Backslash]" )

    even if in both cases 1) and 2), "ù" is interpreted as "[Backslash]".

    I believe you would do this like so:

    [
    {
        "key": "ctrl+\",
        "command": "editor.action.commentLine",
        "when": "editorTextFocus && !editorReadonly"
    },
    {
        "key": "ctrl+y",
        "command": "-editor.action.commentLine",
        "when": "editorTextFocus && !editorReadonly"
    },
]
