4. Commands Use the Control Key You issue most commands in Pico by holding down the Control key and typing a letter. A caret (^) is used to indicate the Control key. To issue the Get Help command (^G), for example, hold down the Control key and type g. Marking, Cutting, and Pasting You cannot use your mouse to select text in Pico, so you must mark text you want to cut instead. The command for marking text is ^^. The first ^ indicates that you should hold down the Control key. The second ^ means to type a caret (Shift-6). The mark feature (^^) allows you to mark any segment of text, cut it out (^K), move the cursor, and paste the text (^U) in the new location.
