Welcome back to emacs rocks

Today we're taking a look at two of my favorite ways of jumping around

First out is ace-jump-mode

I want to jump to the word "strict" in that "use strict" declaration at the top

Wow, that was fast!

Now, the third instance of the word rows in that return statement

Again, straight to it!

And I can jump straight back to where I started by popping the mark

Okay, let's do that in slower motion

I initialize ace-jump-mode,

and then type the starting letter of the word I want to jump to: S

notice how everything is greyed out, and the S is replaced by a red A

I press A

Next up is the word rows, starts with R

See how all the words starting with R has its own letter?

The one I want is number five from the top, or E

Again, pop mark to get back

I can also jump into the middle of a word

by giving ace-jump-mode a prefix argument

Like to the word "shape" in validateNonEmptyShape

That was ace-jump-mode

And it is ... ace!

Next up is ido-imenu

Depending on your major mode, it find symbols in the buffer

and lets you jump quickly to them.

I'd like to use pop-mark to jump back here aswell

but ido-imenu doesn't set the mark before jumping.

Luckily we're using a truly extensible editor,

so I fixed that.

Here's the script

and you can find it at this gist.
