[Lazarus] How to detect that the Alt-key is released?

[JuuS]

Sorry I confused you, my specialty.

What I meant was if you use the 'ssAlt in Shift' line, it won't work if
you only press the alt key because in a keyup handler the key is then
up! And so won't pass the if statement. It would work in a keydown
handler though.

if you press and hold alt and then press and release, for example, 'a'
you will see it catch the state of the alt key.

as to the vk_menu, no idea. But to detect states of shift, control, alt,
etc. the methods I showed are what is normally used.
