Hi guys,
There's a technique that I use sometimes, where I use a "library" file of chord notes that I can quickly copy into a different file. The library file is in key of C. If I need the notes to be in a different key or chord (eg. G), it's easy enough to (1) click-drag to select the notes and (2) use "P + up/down arrow key" to shift the pitches to the proper chord.

Please feel free to use it, or expand on it. These are only basic chords, and don't have any extensions or slash bass notes.
ttfn,
Sherry
