I’ve been a fan of ace-jump-mode ever since I saw Magnar Sveen’s outstanding video on jumping around. Development on the package has gone dormant but abo-abo came to the rescue with avy. I’ve written about avy previously and agree with others writing on it that avy is a significant improvement on the original ace-jump-mode.
Bozhidar Batsov has a a few words to say about it too. Like the rest of us, he is celebrating the replacement of ace-jump-mode with avy and his post mentions something I didn’t know. If you have to work with camel case identifiers, the avy-goto-word-or-subword-1 function will do the right thing. I’d sooner take a pencil in the eye than use camel case but not everyone feels that way or has an option. If you’re one of those people, take a look at avy-goto-word-or-subword-1. It may be just what you need.
