If your native language is not English, you probably have two keyboard layouts installed and switch between them using Alt+Shift. This is fine, but if you're learning some third language or you just need to type in yet another layout occasionally, this becomes rather annoying because Alt+Shift doesn't work like Alt+Tab, so if you press it once to switch from English to your native language, then press it once more, you end up with third layout instead of going back to English.

This script aims to fix that issue, allowing to switch between two layouts no matter how many of them you have enabled in Windows:

; This should be replaced by whatever your native language is. See 
; http://msdn.microsoft.com/en-us/library/dd318693%28v=vs.85%29.aspx
; for the language identifiers list.
ru := DllCall("LoadKeyboardLayout", "Str", "00000419", "Int", 1)
en := DllCall("LoadKeyboardLayout", "Str", "00000409", "Int", 1)

!Shift::
w := DllCall("GetForegroundWindow")
pid := DllCall("GetWindowThreadProcessId", "UInt", w, "Ptr", 0)
l := DllCall("GetKeyboardLayout", "UInt", pid)
if (l = en)
{
    PostMessage 0x50, 0, %ru%,, A
}
else
{
    PostMessage 0x50, 0, %en%,, A
}

Known problems:

[*:okyfdnxp]The code above works only if you press Alt first, then Shift. If you press Shift first then Alt, normal layout switching mechanism is used. If you don't like this behavior, it is quite easy to change it to work for Shift-Alt too.
[*:okyfdnxp]The layout is switched as soon as Shift is pressed. This is different from the way Windows handles it, when switching occurs when you release one of the keys, provided you didn't press anything else in-between. This could be annoying if you use some shortcuts like Alt+Shift+V somewhere. A workaround is to press Shift+Alt+V instead, but it requires some practice to get used to it.

Hi guys,

 

Is there any way to directly switch keyboard in Autohotkey? Like, left Win for the first layout and right Win for the second one.

 

I gues it also implies moving the Win keys somewhere else.

 

Thanks!

Hi,

 

does anybody here use Dvorak Programmer keyboard (http://kaufmann.no/d...i386-calc.exe)? 

 

If so then how to make the trick in thread to work with that layout?

 

R. Kaufmann (the author of layout) told me magic constants as follows:

 

dvp := DllCall("LoadKeyboardLayout", "Str", "19360419", "Int", 17)

// the latter parameter should at least include KLF_REPLACELANG (= 0x10, i.e. the sum in the last parameter should at least be 16+1 = 17) see: https://msdn.microso...5(v=vs.85).aspx

// one could experiment by passing INPUTLANGCHANGE_FORWARD (= 2) as the second parameter to PostMessage (WM_INPUTLANGCHANGEREQUEST (= 0x50))

 

But nothing worked out. Any ideas on how to make it work?
