I was starting to feel some hand strain while playing minecraft from holding down the left mouse button, so I was looking for some kind of setting that would let me toggle the left mouse button instead of needing to hold it down.
I didn’t find a minecraft setting for it, but I did find this instead:
Typing
xte "mousedown 1"on a console seems to do what you’re looking for. It simulated a click and hold of the first mouse button. The button appears to stay clicked until I click another mouse button.
I was able to find a reference to xte on the Arch Linux wiki as well, confirming that the xte tool is in the xautomation package:
xte from xautomation comes handy when we want to bind keyboard buttons to mouse.
Using this information, I installed xte with pacman -S xautomation and then set a keybinding in my settings to run xte "mousedown 1" on a key combination, which let me hold the left mouse button down like I wanted to.
