Hi folks, I have a question regarding key changes, or transpositions.

Here's what I'm doing in BIAB 9: I'm writing long songs with many sections (using the "one long song" technique, no auto repeats) they sound great but I need to experiment more with key changes to add variety.

1. Is it correct that I can only transpose the entire song? I can't select a portion of it and just transpose that?

2. What is a good way to try out different key changes to see how they sound?

3. Is it only possible to have one BIAB document open at a time?

Because here's what I've been doing--- I copy the chord progression (say 8 bars) I want to transpose into a new document, transpose it, copy it to the clipboard, and paste it back into the song I'm working on. Try it. Nope, close song, open transposing doc, try another... awkward method, but it works. Sometimes I simply write down the transposed chord symbols, then I can try a bunch of different ones without having to open and close the documents multiple times.

Forgive me if this seems outrageously Newbish. Is there a better way? How to other people do this?

Thanks for your help! Bandmoose.
