Two uses for [F4] in PowerPoint (2000/2002/2003/2004/2007)

[F4] is a handy shortcut that you can use in a few ways in PowerPoint presentations. Pressing [F4] allows you to repeat the last action you performed. For example, if you just increased the font size of a block of text, you can select another text block, press [F4], and have your changes repeated there. It also works to duplicate objects that were just created and apply font sizes. You can repeat almost any action that requires only one button click by pressing [F4]. If you press [Ctrl][F4], something very different happens: you close out of your presentation.
