I just started up Roll20 for the first time on a new computer, and I tried placing some tokens without having them snap to grid, but Firefox doesn't like me using the ALT key over and over again. It's already bound to a command that brings up the menu at the top of the browser, which sort of causes the tabletop to refresh. I've looked at some FF extensions to rebind keys but none of them can rebind that particular key. Is there any way to rebind the snap-to-grid toggle to something that isn't ALT?
