I'm very keen on Excel keyboard shortcuts, but somehow I've never noticed this before: using control plus the arrow keys will jump you to the left, right, top or bottom of a fixed block of data. Very handy for navigating complex spreadsheets.
In the other Office apps (and many other apps generally), Control plus a key jumps either a word at a time (left and right) or a paragraph at a time (up and down). I imagine the equivalent Cmd key shortcuts also work in Office for Mac, but I can't confirm that directly. For more Excel shortcuts, check out our listing of the six most useful shortcuts.
