As an alternative to AutoIt, there is AutoHotkey.
First, you can do one-liner (save it as *.ahk to your startup folder, which is opened fastest way as Win+R, Shell:Startup
, Enter):
^Space::#Space
Basically, it sends Win+Space when you press Ctrl+Space.
Similarly with Alt+Space:
!Space::#Space
If you add following to start of script, it will only take ~100-200kb of RAM. Otherwise, around 3 MB.
#NoEnv
#NoTrayIcon
;save a bit on memory if Windows 5 or newer - MilesAhead
DllCall("psapi.dll\EmptyWorkingSet", "Int", -1, "Int")
Alternatively, there is scripts for this which sends "switch layout" message instead of relying on sending Win+Space. It also should be running in background. In current variant, it switches layout when Right Control is tapped, but it's easily modified in two lines starting with $~RControl
.
