Here's a gem from Micahel Hall:

If you're using Place Note to place leader lines but not text, change the command to read:

place note icon;dmsg closedialog 1 wordproc

Note: This keyin does not work in V8i.

The word processor will still flash on the screen, but won't take up any precious real estate.

Note, to learn more about the keyins used to dismiss dialogs, refer to this article:
