Grant over at Wisdom and Wonder has a short post that points us to imenu-list. That’s a minor mode that puts the output of imenu into a separate buffer where you may find it easier to work with. If you follow the link to imenu-list‘s GitHub page you can see a screen shot of it in action.
Somehow, I’ve never warmed up to imenu but perhaps this will help. You can think of imenu-list as being sort of like occur and use it in a similar way. If you find yourself jumping around a program buffer a lot, you may want to give imenu-list a try.
