Add (or replace!) functionality of a menu command in BBEdit with a script! SHOWNOTES BELOW:
Where I got the BBEdit menu script from:

Something I forgot to mention: usually menu scripts happen before or after BBEdit's normal functionality. However, if you return true it means, "This script has handled the menu command in its entirety - do not continue."
