Using scan code in hotkey variant fire both hotkeys

[axelgauffre]

Hi my friends,

I've been struggling with the probleme below for hours.
I searched the forum and Google but couldn't find any answer to my question.

Watch the following script.
When I use ~*Escape or ~*VK1B (VK1B is the virtual key for the Escape key) for my second hotkey, the script behaves has espected, that is to say, when I press Escape, only the first Msgbox is displayed.
Now, when I use ~*SC001 (SC001 is the scan code for the Escape key) for my second hotkey, strangely , when I press Escape, both the first and second Msgbox are displayed!!

Could anyone tell me why?

Thank you for your time and help.

(I am on Windows 10 with AHK 1.1.23.05)

Code: Select all

#SingleInstance force

Escape::
	MsgBox % 1 A_ThisHotkey
	Return

~*SC001::
;~*Escape::
;~*VK1B::
	MsgBox % 2 A_ThisHotkey
	Return

Based on this link, scan codes (SC) are more hardware dependent. I'm guessing that they simply point to other key names (rather than being replacements for them), so ~*SC001 invokes the key named "Escape"... and because you're using the ~ prefix, your hotkey code for Escape is also being sent, resulting in both message boxes. It seems that VK codes are more a substitute for key names, rather than pointers to them, so they behave more normally and predictably. Of course, you can easily fix this situation by removing the ~ prefix from the SC code, but, if you're looking more for an explanation, that's my guess at what's going on.

Thank you anyway for your "guess" Osprey .

However, if anyone has a more precise answer I would still like to hear it.
