Unity launcher / OSX Spotlight like functionality for administration? I'm fairly certain I've seen a module that provides a quick way of typing in, for example, the title, of an administrative page, and it would wisk you away to that page.

Much like the way Unity's launcher, OSX's spotlight or KDE's runner behaves, just inside your site instead of the desktop.

However, I can't seem to recall what it was called and google only came up with this abandoned sandbox.
While coffee is probably the module you are looking for, i think switching on search in admin_menu is way more productive - no roundtrip for the searches and you stay focused on the admin stuff. I bet you are using the admin_menu anyway ? Just visit admin/config/administration/admin_menu and hit save - the search field should appear on the right hand side of the admin menu :)
