the ^ character
Pico makes wides use of "control key sequences," represented in writing as commands starting with a caret (^). Lines that have a ^ followed by a letter, are actually typed as commands by pressing the Control key and typing the character (while you are holding the control key down). For example, the command for deleting a line is control-k, represented in writing as
^k
To actually type this command, you hold down the control key while you type the lower-case letter k.
finding pico's commands
All pico commands are displayed along the bottom of the pico screen. So if you need to accomplish a task in pico and don't know what the command is to do that, the bottom of the screen should be the first place you look.
