I want to move the mouse with one hand while with the other making the button clicks with the keyboard.
The difficult part was to instruct AutoHotKey to hold down the mouse button while holding down the key on the keyboard. So you be able to click and drag.
It makes the clicks with the 1, 2 and 3 keys at the keyboard, in inverse order (left click with the 3, as preserving left click with the index finger but of the other hand, trying to mirror the workings inside the brains hemisphere, or something)
This script is activated while ScrollLock is ON (finally some good use for that beautiful and neglected key, activating all sorts of keyboard shortcuts for AutoHotKey)
