Area(s) with issue?

Mouse Without Borders

Steps to reproduce

1. Run KeepassXC with global auto-type enabled and the default (I think) hotkey of Ctrl+Shift+Alt+K.
2. Press Ctrl+Shift+Alt+K to show the auto-type popup. (Esc to close.)
3. Run PowerToys and enable Mouse Without Borders.
4. Press Ctrl+Shift+Alt+K to attempt to show the auto-type popup again.

✔️ Expected Behavior

As no shortcut for Mouse Without Borders has been configured for Ctrl+Shift+Alt+K, I expect the KeepassXC hotkey to be triggered as normal, whether MWB is running or not.

❌ Actual Behavior

Whenever Mouse Without Borders is enabled, KeepassXC's auto-type hotkey, bound to Ctrl+Shift+Alt+K, is non-functional.

Investigating the source shows a hardcoded hotkey Ctrl+Shift+Alt+K:

    if (CtrlDown && altDown)
        if (...)

PowerToys/src/modules/MouseWithoutBorders/App/Class/InputHook.cs

Lines 648 to 655 in 202bb4c

	else if (shiftDown && Setting.Values.VKMap != null && vkCode == (Setting.Values.VKMap.ContainsKey(0) ? (int)Setting.Values.VKMap[0] : 'K'))
	{
	if (Common.DesMachineID == Common.MachineID || Common.DesMachineID == ID.ALL)
	{
	Setting.Values.UseVKMap = !Setting.Values.UseVKMap;
	return Common.DesMachineID == ID.ALL;
	}
	}

It seems Ctrl+Shift+Alt+K toggles the 'Use Key Mappings' option, visible on the old MWB Settings page (or UseVKMap in settings.json).

I'm not sure what this setting is supposed to do. The tooltip refers to http://aka.ms/mm, but I can't see anything relevant there.

The implementation also looks rather suspect -- a property with a getter that returns a new Hashtable on every access? (The above ContainsKey(0) check presumably always fails as a result.)
