Show menu only after a delay if no keys have been pressed

[eugenesvk]

I don't need to see a command palette every time I press LEAD key if I want to do window management, I do it frequently enough to remember that w is window.

Similarly, within the window management submenu, I know that f is fullscreen, etc.

So it would be better to now show such command palette every time as that's just visual noise.

But then obviously I don't remember all the menu items, so if I want to execute some less frequently used/forgotten command the command palette is a very welcome reminder

The best way I've found to resolve this issue in some other script app is via a delay

• if I don't press anything after LEAD within 0.X seconds, then the command palette shows up
• otherwise it silently enables the relevant mode, but doesn't show anything
