Bind those keys!

When you hit F9, you'll see a window with all the keybindings (shortcut keys to you and me). F12 is usually empty, and I like to put the following in:

F12     output; clear; log; clear; wpgm

This clears your output window and your log window and then returns you to the editor window. I like to hit F12 before I submit any new commands, so I don't have to search and scroll through the log and the output, but start with nice shiny new ones.
