When we switch any language to ENG, for example RU to ENG with mouse then we have LCtrl Up pressed event.

If We run this code then after switching any language to ENG with mouse We will get msgbox.

Code: Select all

LCtrl Up:: msgbox

And key history shows this:

Code: Select all

VK  SC	Type	Up/Dn	Elapsed	Key		Window
-------------------------------------------------------------------------------------------------------------
A2  01D	h	u	4.70	LControl       	Program Manager

Is it sent by Autohotkey or by Windows?
And why?

[lexikos]

It is sent by Windows. Why? Ask Microsoft.

If I had to guess, I would say it relates to how Windows handles AltGr (as a combination of LCtrl and RAlt).

[malcev]

You are right!
If I modify existing keyboard layout (remove using AltGr key from it) then it works without sending LCtrl Up.
Thank You very much!
