I would like to write a simple script (one-liner?) to map the left shift + right mouse button to the middle mouse button (I don't actually have a middle mouse button, as it is a trackpad).
I have tried variations of this:
#(LShift & RButton)::MButton
(LShift & RButton::MButton
LShift & RButton::MButton
always with the error
Error: Invalid Hotkey. I came here through the somewhat less specific question:
