I have a tic disorder (not Tourette's, because my tics are all nonverbal). One of my tics is that I mash both mouse buttons over empty space pretty frequently. I even go out of my way to keep my cursor positioned over empty space so I can mash the mouse buttons when I need to, and it's not uncommon for me to move the cursor while mashing the buttons. If the cursor is towards the bottom of the screen, that's pretty much guaranteed to open dev tools, since all it takes is a small motion of the cursor with the right-click menu open to hit the 'Inspect' option.
