Hello,
I find it convenient to be able to go to definitions using the mouse
(especially when getting to know new code bases). I have the below
function bound to C-mouse-1 like so:
(global-set-key [C-mouse-1] 'xref-find-definitions-at-mouse)
(global-set-key [C-down-mouse-1] nil)
I also find it convenient to be able to get back to where I was using
only the mouse (enabling keyboard-free navigation):
(global-set-key [C-mouse-3] 'xref-pop-marker-stack)
(global-set-key [C-down-mouse-3] nil)
Finding suitable default keybindings (well, "mouse bindings") is beyond
the scope of this patch, but what I have above is the same binding as
other popular IDEs such as IntelliJ and VS Code.
Regards,
Tobias Gerdin
