Yes. A common mouse design has a left and right button (1 and 3
respectively; can be reversed for left-handed users), a scroll wheel
(button 2 when clicked; 4 and 5 when turned up and down; on some
models, it can also be tilted left and right for horizontal scrolling,
X11 calls this buttons 6 and 7), and one or two thumb buttons (one for
going back in browser history, another forward; these are numbered 8
and 9).

Popping mark in general, and going back from a “find definition”, are
sufficiently semantically close to a “browser back” to be bound to the
same button.
