The font-resizing shortcut
Want to make your font size larger or smaller without going to the Size setting in the Options Bar? This one is really easy. Double-click the Type layer thumbnail to select your type. Then press Command-Shift-> (PC: Ctrl-Shift->) to make your font larger or Press Command-Shift-< (PC: Ctrl-Shift-<) to make it smaller. Bonus tip: Add the Option (PC: Alt) key to the mix and the size will change in increments of 10.
