Newbie problem

[john s.]

Having had no trouble generating a key pair, I am having some problems of
understanding.

I am going around in circles trying to understand something i am sure is quite
straightforward.

The command:

	gpg --edit-key UID takes me to a command prompt and suggests I check
help. What do I do now? I wish to extend the the expiry date of my key which I
initially set at one year
