Linux text-editing question

[Ned]

HI all,
I just came back from my Unix class and my teacher is getting desparate with 
me. I used pico to write a little paragraph -- which went ok until I tried 
to go back to some words to correct them. Because we use putty, I can't 
focus the cursor on a particular letter to -- say -- delete it, and 
everything got mmessed up. Then using VI, Iwas supposed to edit a paragraph 
of text. After he saw what I did, he went speachless. SO tell me, is there 
any other more friendly remote client like telnet or something.
Plese people, encourage me in these tough times and tell me what to do? I 
appologize for posting a question little off the topic, but putty is 
actually using Unix commands sent to it from the machine running it.

Many thanks in advance good people.
Ned
