Can't toggle mark mode using the keyboard shortcut (Ctrl+Shift+M) / mark mode disappeared?

Steps to reproduce

• remove settings.json to have it regenerated by WT
• open WT
• try pressing ctrl+shift+m
• nothing happens

You could also try adding this to your config (below config is abbreviated):

    "actions":
    [
        {
            "command": "toggleMarkMode",
            "id": "Terminal.ToggleMarkMode"
        }
    ],
    "keybindings": 
    [
        {
            "id": "Terminal.ToggleMarkMode",
            "keys": "ctrl+shift+m"
        }
    ],

Expected Behavior

I expect mark mode to be toggled by the default keyboard shortcut. It is bound by default in Settings -> Actions -> Toggle mark mode: ctrl+shift+m.

Oh and also, the docs aren't up to date from what I can see. I was unable to add "toggleMarkMode" to the actions array in settings.json like this:

    "actions":
    [
        {
            "command":
            {
                "action": "toggleMarkMode",
                "input": "",
                "keys": "ctrl+shift+m"
            }
        }
    ],

In fact, "toggleMarkMode" doesn't show up in vscode's autocomplete anymore, like the other settings do.

Actual Behavior

Nothing. I am able to toggle mark mode by opening the command palette and searching for "toggle mark mode" however.

Curious! Is there a chance something else on your system is hooking Ctrl+Shift+M? None of us here can reproduce this issue.

I was able to reproduce this issue on Windows Terminal 1.23.x.

Using the new-style configuration (actions + keybindings), I added:

• an action with the command "toggleMarkMode"
• a keybinding referencing that action id (ctrl+shift+m)

The keybinding does not trigger any behavior, while the same command works correctly when invoked from the Command Palette ("Toggle Mark Mode").

This indicates that toggleMarkMode is available as a Command Palette action but is not properly exposed or handled by the keybinding action map. This appears to be a missing or incomplete action registration rather than a configuration issue.

Thanks for confirming, @udaysahu09.

@DHowett, I do have AutoHotKey installed but disabling or uninstalling it doesn't make a difference.

Curious. @bigtanuki64 if you add a key binding for ctrl+shift+m to Terminal.OpenNewTab:

        {
            "id": "Terminal.OpenNewTab",
            "keys": "ctrl+shift+m"
        }

Does it open a new tab? You can compare it with Ctrl+Shift+T.

@DHowett It doesn't open a new tab, no. I wonder if you're right that there's something else hijacking that specific shortcut, but I can't find any suspicious background apps... Here are my action and keybinding arrays from settings.json:

"actions": 
    [
        {
            "command": 
            {

            },
            "id": "User.scrollUp.0"
        },
        {
            "command": "scrollDownPage",
