Is there a way to specify a Tab indent of 2 spaces for the B4J IDE editor instead of 4 spaces?
(B4A uses 2 spaces for indenting and I've become used to that.)
Well, as very often RTFM !
You could also have had a look at the B4J Beginner's Guide page 53 and 66.
But the Beginner's Guides are getting obsolete, so I promote the B4X Booklets.
