InsertMode binds with<C-Key> in settings.json doesn't work.

[paupalou]

Describe the bug
Bind combinations of Control + key in settings.json when Insert mode is active (vim.insertModeKeyBindings) writes the textkeys instead doing the "keypress".

To Reproduce
Steps to reproduce the behavior:

1. Edit settings.json, useCtrlKeys should be true.

2. Add those keybindings
   { "before": [ "<ctrl-a>" ], "after": [ "<Esc>", "I" ] }
{ "before": [ "<ctrl-e>" ], "after": [ "<Esc>", "A" ] }

3. Open file , start insert mode then press Control-A , it should go to start-of-line, or with Control-E should go to end-of-line

4. Cursor doesnt move, just writed some characters (from copy register i think)

Expected behavior
Would be fine the possibility to add those bindings in settings.json , i finally made it working editing keybindings.json.
{
"key": "ctrl+e",
"command": "cursorEnd",
"when": "editorTextFocus && vim.active && !inDebugRepl && vim.mode == 'Insert'"
},
{
"key": "ctrl+a",
"command": "cursorHome",
"when": "editorTextFocus && vim.active && !inDebugRepl && vim.mode == 'Insert'"
}

Thanks!

I have a similar problem: setting:

{"before": ["<C-a>"], "commands": ["cursorHome"]}

Caused the cursor to move correctly, but <Esc> stopped working in insert mode. Checking the debug log level, it appears <Esc> wasn't even being detected.

Faced the same issue.
Trying to do the following:

"vim.insertModeKeyBindings": [
   { "before": ["<C-e>"], "commands": ["cursorLineEnd"] }
]

If I press Ctrl+E once I can see that the key combination is handled, but the mapping is not triggered:
[Extension Host] debug: ModeHandler: handling key=<C-e>.

If I press it two times in a row, the mappings looks to be found, but nothing happens with the cursor, the standard Ctrl+e behavior is still triggered (copying characters from the line below). Here's the console output:

console.ts:134 [Extension Host] debug: Remapper: insertModeKeyBindings. before=<C-e>. command=cursorLineEnd. args=.
2console.ts:134 [Extension Host] debug: Remapper: find matching remap. keys=i,<C-e>,<C-e>. mode=Insert.```
