I noticed that there are guides for keystates in the help files.

But, how do we detect keys that were not listed?

I tried to find out what keystate F4 and ALT key was assigned to, but there are no command that detect what keys are being pressed.

So, how do we get keystate number for keys that are not listed in the help file (such as ALT and F4 keys)?

Google Keycodes and you'll find numerous maps, like...

You can see the keycode for the last pressed key with this:

GetRawLastKey()

EDIT:

This code does not work, it seems as if no more key will be detected when holding down the ALT key :-(

Something weird happened. It is as you said.

GetRawLastKey() detect F4 as 115, and ALT as 18

When ALT key is pressed WHILE the F4 key are being held down, then it works.

But,

If the F4 key are being pressed WHILE the ALT key are being held down, then only the F4 keys are being registered. ALT key is not in this case.
It deosnt matter what keys i wrote firstt on the code, but the result is the same.

A bug I suppose.

In this case, F4 is the last key pressed. It can only hold one value at a time.

You need getRawKeyState() which works on multiple key presses at the same time, I just tested.

You mean, like this?
I used it to end the program


IF GetRawKeyState( 18 ) > 0 AND GetRawKeyState( 115 ) > 0
END
ENDIF


If the F4 pressed first, then it works.
IF ALT pressed first, then it doesn't

getRawKeyState() can detect multiple key presses, but somehow it doesn't detect F4 key if ALT key is pressed first.

I understand the issue now, and actually, it's worse than you think!
If you try the following Key sequence, the F4 key state gets stuck at 1, even after you stop pressing:

F4 DOWN
ALT DOWN
F4 UP
ALT UP

Is this bug worth reporting?

Where do we properly report bugs anyway?

Yes, I would suggest reporting it. Create a new thread starting the title with BUG:
