[NTLUG:Discuss] VI editor commands

[jay linux]

I'm refamiliarizing myself with the VI editor after a long, long time....

Can anyone tell how I can:

1) Find all words that start and end with a vowel.
2) replace all occurances of xxx, yyy, and zzz with Xxx, Yyy, and Zzz. In 
otherwords, cap the first letter of multiple words in a single VI command.

Thanks, Jay
