A productivity boost for all writers — deleting entire words in a keystroke:

Hot off the presses from Lifehacker headquarters LA (i.e., just discovered this morning in my dining room-cum-office) comes my favorite new keyboard shortcut, Control-Backspace (Windows)/Option-Delete (Mac).

Ctrl-Backspace/Option-Delete will delete the entire word to the left of your cursor in one keystroke, meaning no holding down and waiting to individually delete every letter from Supercalifragilisticexpialidocious – the swift shortcut will take care of the whole word in one fell swoop. Source
