ESC < does not work when using ggtags to navigate source files

Question

I have been using ESC-< or Alt-< to jump to the beginning of the file. After I added ggtags for source navigation, normally it works. But after I press Alt-. to find the declaration/definition of some method/class/variable, pressing ESC-< or Alt-< will instead navigate me back to the previous point from which I pressed Alt-. to navigate to the method or class.

I can still use Alt-g g 1 to go to the beginning of the file. But is there a way to still use ESC-< to go the beginning and assign different binding for ggtags to return to previous position?

Answer 1

It looks like ggtags rebinds M-< to #'first-error in the keymap ggtags-navigation-map.

So we can unbind it there:

(define-key ggtags-navigation-map (kbd "M-<") nil)

And bind something else to it:

(define-key ggtags-navigation-map (kbd "C-M-<") #'first-error)

Obviously, you can pick another keybinding, as you prefer.
