You can also search and do multiple selection with a regular expression, which is awesome. I've used this heavily in the past few weeks. The only problem I've had is that all searches appear to run on the main thread, so when working on a sufficiently large file, the whole application blocks like hell. And to make it even worse, they update search results on the fly, meaning that for every new character you enter it blocks. I've taken to writing my expressions fully in a random textfield elsewhere, and pasting them in all at once.
