I apologize for the basic question, but I am not facile with coding and I really did try to find the answer before asking.
I wish to have macros triggered by (a Logitech multi-buttoned) mouse. Moreover, I need to have said macros initiated within specific applications. (I can only find mouse activity as executable actions.)
My "macros" are nothing more complicated than a sequence of keystrokes.
Again, sorry for my ignorance. I am specifically asking how to use a mouse click as a trigger. I do not see any applicable choices under the "new trigger" items for mouse clicks.
