General Tip: Command () + Enter For Entering to Cell View
 

Just found out this keyboard shortcut, which is ridiculously useful. It also means that I no longer need to touch the trackpad at all, which is fantastic.

Command ()+Enter in order to shift from the text entry mode to the row selection mode.

This combines fantastically with Command ()+", which allows you to enter/exit note-entry mode for an individual cell/row.
