Ever wanted to hide the left+right pane’s within Lightroom without having either custom defined shortcuts, or modifying OS X keyboard preferences to enable function keys?
Can’t believe I stumbled onto this shortcut, as its exactly what I wanted to do.

So I went about pressing everything I could - and by mistake I came upon the following shortcut.
Fn + Tab
Which hides both - your left and right panes.
Quite useful for both development view [at least until Adobe decides to provide secondary monitor support], and grid view.
.. and After:
