I am having huge difficulty assigning the letter 'Q' on my keyboard to perform as a left mouse button, including the actions left-click, double-click and hold/drag.
It seems like the simplest task for BTT and yet I have been unsuccessful in making this happen!
I have major tendon damage on my right arm and I am trying to decrease the usage of my right hand, so I thought assigning the left click to a keyboard key for my left hand would be a good starting point.
This is a bit complicated because you need to add two different shortcuts, one for when the Q key is down, and one for when it's up.
Then you need to use the predefined action "More Mouse Buttons & Modifiers" to trigger a left mouse down when the key-down shortcut is triggered and a "left mouse up" when a key-up shortcut is triggered
You can copy & paste these two jsons into BTT (just cmd+c here and cmd+v in BTT):
