I Command It

If you need to use the Command Prompt frequently, here's a feature that can help make your life easier. Let's say you've been working with some MS-DOS programs, and by this time you've entered quite a few commands. If you'd like to reuse some of those commands, or at least see what you've done, press F7. Your command history will pop up in the Command Prompt window. You can scroll through the commands and press Enter to execute a selected command.
