In the upper-left corner of the screen, you will see the version of pico that you are using. To the right of the version number, you will see the name of the file that you are creating (e.g., File: testfile).
Across the bottom of the screen, you will see the options that are available to you. The "^" character represents the CONTROL key. To select one of these options, you must press the CONTROL key and the corresponding letter key at the same time. For example, to "Get Help," press the CONTROL key and the letter G key at the same time.
To delete a line ("Cut Text"), use the ^K option; To undelete a line ("UnCut Text"), use the ^U option.
