First, my apologies if this is not directly related to KM.
Some time ago (possibly following instructions given by someone on this forum) I set up my keyboard so that if I selected some text and pressed the Control key, the selected text would be copied. Recently this has stopped working and I can’t figure out why or how to restore this function. Can someone point me in the right direction? (I am running El Capitan.)
I have Karabiner installed, and the USB Device key trigger does indeed not seem to work. But I don’t think this is the cause of the problem here. Hammerspoon looks a bit beyond my capabilities, but I will have a look at BetterTouchTool.
And I would really like to know how I set up the Control key in the first place to copy text.
