set object mode in sculpt mode quick favorites, and put sculpt mode into object mode quick favorites. I recommend you do it as well
here is how
you click on that dropdown for modes
then you right-click on sculpt mode or your other desired mode, and it should have the option, “add to quick favorites”
now all you need to do is click q and left click.
be sure to set it vice versa in the opposite mode
edit: hadn’t seen the whole video when I made this, well that invalidates my system now doesn’t it
