Firemonkey working with Alt + Char

My goal is to hook the Alt key and while it is down, process the next char pressed as a shortcut key, the way the Ctl key works in a TMenuItem.

I tried the FormKeyUp event but it never returns ssAlt in the Shift parameter.

How can I accomplish this? Is there any Windows message that I can hook to detect that the Alt key is down?

Look at `GetKeyState()` and `GetAsyncKeyState()` in the Win32 API – Remy Lebeau Jul 28 '18 at 09:48
@Remy. I wonder why is it that the `FormKeyUp` event does not return the proper values in case of the `Alt`key. Do you have any clue? – user2383818 Sep 07 '19 at 20:16
