Please I need to attack with keyboard.

Like A for move but another keystroke to stationary attack, or left mouse, I suffer from hand pain and its hard to press the left mouse button so much, pls do this I beg you.

I know this doesn’t answer your question but, did you consider using 3rd party software as a temporary workaround? I’m sure there is something out there that can bind your mouseclick to a keybind.
