I've been on a bit of a Keyboard-only kick lately, enabled chiefly due to the Chrome Keyboard Shortcut Extension, and I've begun bumping into a few difficult situations in everyday Desktop App use.
In applications like iTunes, or Code Editors, they have a unified sidebar with categorically organized content. iTunes has categories for your library, other people's libraries, your device, and playlists, Coda has a file picker, etc. But what is the easiest way to move keyboard focus to these sidebars? My current solution is to alternate Tab and ▼ aimlessly until I see an item on the sidebar highlighted. Needless to say this is frustrating and can lead to unintended changes being made in content panes.
I notice that most all apps have a function to hide the sidebar in the app menus, but restoring it doesn't move the focus to the sidebar.
I've looked at the Mac OS X Keyboard Shortcut Question but didn't find what I was looking for. Is there some kind of a global shortcut that will move focus between different interface elements, easily? Reliably?
