VS Code -- Caps Lock to Backspace

keybindings.json

// Place your key bindings in this file to overwrite the defaults
[
    {
        "key": "capslock",
        "command": "replacePreviousChar",
        "args": {
            "text": "",
            "replaceCharCnt": 1},
        "when": "editorTextFocus"
    }
]

I noticed that, at least on Linux GNOME 3.26, Visual Studio Code uses the system keyboard layout -- with the exception of backspace not working. Digging through the sparse documentation on commands and looking at some code examples, I figured out that this config snippet will do to restore the functionality of the CapsLock key for other Colemak users!

It's good, but not perfect. Do you know how to remove a text that has been selected?

Edit:

[
    {
        "key": "capslock",
        "command": "deleteLeft",
        "when": "editorTextFocus && !editorReadonly" 
    }
]

Hmm this maps to deleteLeft ... in the editor only, that's nice :- )
and I'm wondering, is there no way to map it to Backspace, always, in each and every situation.

(I'm using Vim mode & Colemak, so caps-lock/backspace could be useful in many many more cases)

Edit 1 month later, this works fine this far, with VSCode and Vim and Colemak:

        "key": "capslock",
        "command": "extension.vim_backspace",
        "when": "editorTextFocus && vim.active && !inDebugRepl"
