Alt+Tab is Windows's built-in to focus a different window. Lix doesn't trigger the focussing/unfocussing, Windows does.
Ah, that explains why it sometimes auto-switches to Explorer view or other Desktop applications. Another reason I don't favour this hotkey combo, but good to know why it's happening.
What do you expect from a custom hotkey that Alt+Tab doesn't give you?
Merely easier to press?
Don't undermine/underestimate ease of use.
Hitting 2 keys vs hitting 1 key is already 50% less efficient. Factor in that one of these keys must be held whilst hitting the other, and you could argue it's up to 75% less efficient than just hitting one key.
Splitting hairs, maybe, but improvement is improvement.
Have you activated Options -> Controls -> Fast Movement Untraps Mouse?
What problems does that option have?
To be fair, it's probably my own fault that I have issues with the fast-movement mechanism.
Like with most other windowed software than I use, I have the window edges almost to the edge of the screen. I do this so that I can access the desktop and taskbar easily, but still get almost a full screen's worth of app. With this being the case, it's far too easy for the mouse to drift back into the Lix window and get re-trapped.
So, to answer the second part of this - my problem is more due to my chosen window size than with the speed of the untrap mechanism itself.
Maybe the app shouldn't re-trap unless directly interacted with? I'm pretty sure Neo/SuperLemmix behaves this way (i.e. once untrapped, you can drift the cursor across the window without the app trapping it again).
You can untrap with the Win key as well I think.
Indeed you can. But, this also opens the Windows menu, which must then be closed. Hitting the Win key twice
is better than Alt+Tab, admittedly. It's still 50% less efficient than a single hotkey, but - again - maybe I'm being a bit pedantic here.
Thinking about it,
the behaviour I'm actually after is for Lix not to re-trap the mouse unless directly interacted with. Then, fast movement to untrap would be fine.
