So it should also be possible to set up a function key to just do that, right?
Or disable for example the left windows key and use that as a modifier?
To disable Left Win Key and use it as a modifier to do the same thing:
Lwin::return
LWin & 0::SendInput, {Raw}/
LWin & u::SendInput, {Raw}4
LWin & i::SendInput, {Raw}5
LWin & o::SendInput, {Raw}6
LWin & p::SendInput, {Raw}*
LWin & j::SendInput, {Raw}1
LWin & k::SendInput, {Raw}2
LWin & l::SendInput, {Raw}3
LWin & m::SendInput, {Raw}0
LWin & `;::SendInput, {Raw}-
LWin & /::SendInput, {Raw}+
To run AutoHotkey scripts, you need to install AutoHotkey
(download
here. I recomend the improved AutoHotkey_L version).
As said before, Autohotkey site is the best place to start with.
You can run your scripts directly (double click .ahk file) or compile them into an exe.
