7.2.4 Shortcut Keys

In the CLI, you can use shortcut keys to make editing commands a little easier:

• backspace, del, left/right arrow keys: they allow you to edit a command line.
• up/down arrow keys: they select a command from a history of commands that you have used recently. The up-arrow key goes up in history (more ancient), and the down-arrow key goes down in history (more recent).
• tab: you can use the tab key to perform ``file name completion''. This means if you have a file called abcdefgh.txt in the current directory, you can type abc, then use the tab key so the CLI completes the entire filename for you. If there are multiple files starting with abc, you can press tab one more time to list all such files.
