The Community Net Keymap does not operate in Pine, it has instead its own sets of commands in its different sections. The basics of editing are the same as for the Pico editor detailed later in this document. Look there for a detailed description of editing the message. The top part of the composing screen contains a header for the address and some information about sending it. Below this is the actual message.
Arrow keys Move the cursor around.
Send Finish composing this message and send it off to the addressees. Cancel Stop sending this message. Anything you have composed is lost. You have a chance to confirm cancellation. Giving this command again hides these fields again but does not remove the information.
