Hi Bob. Yes, as Mac said, Xmaj7b5 works.

I normally write that chord in a chart as Xmaj7#11, but as Ray pointed out, you have to enter it as Xmaj9#11 since BIAB doesn't support Xmaj7#11.

However, you can enter Xmaj7#11 as a shortcut for Xmaj9#11 (or for Xmaj7b5 if you prefer that sound) to prevent data entry stumbles.

The two files you are looking for are pgshortc.txt which explains the technique (such as why "h" works), and references you to shortcut.txt where you enter your own chord shortcuts. Both are in the /BB folder. Enjoy!
