changing key

I'd never thought about cutting bits out of a capo before! I guess that way too, you can revert to standard tuning with the snap of a finger!

Also, for quoting, you can copy th specific part you want to quote, and when typing you message, paste it between (quote)(/quote), or press the little icon with the page and blue arrow on it.

Capo's don't have much to do with barre chords. Barre chords are used for a particular sound and the muting action you can get from the fret hand, just as open chords are used for a particular sound. If a songwriter wants a song in open chords and needs to change the key of the song they can use a capo so the song stays in open chords, they are also great to use with two guitars when one is played without a capo and the other guitar uses a capo on a certain fret and plays the same sounding chords. For example if you play an open A chord without a capo on one guitar and the other uses a capo on the 3rd fret and plays a G shape the tonality is that of an A chord and the two plalyed together produce a much better sound than both guitars playing the open A without a capo.
