Is there any way to navigate files in Coda using the keyboard? I love most things about Coda, but having to use the mouse to find and open files is a bit of a pain. Hopefully I'm missing something obvious.
What you really want is SwitchFocus: http://habitatus.net/blog/2009/08/switch-focus-coda-plugin/
There are a couple of caveats. Make sure you read the comments that other people have submitted; they are helpful in getting you reasonable behavior in the sidebar file browser.
