Subject: 24.0.50; indenting region with TAB deactivates region
Date: Sun, 06 Mar 2011 17:22:03 +0100

This is a wishlist bug, since it seems quite usefull if it was possible
to indent a region several times without the necessity to reactivate the
region:

 - Start Emacs (emacs -Q)
 - Set text-mode in the *scratch* buffer. (text-mode).
 - Select the first 3 lines.
 - Type <TAB>

What I was expecting:
 - The selected lines move to the next tab-stop.
 - The region remains active, so that I can repeat the indentation
   several times in a row.

What I see:
 - The indentation of the lines depends on emacs version
   (regression bug filed as bug #8187, see
    http://debbugs.gnu.org/cgi/bugreport.cgi?bug=8187)
 - The region is deactivated.

This bug report is about deactivating the region.  I don't know if it's
easy to fix this but it would be nice if it would be possible to indent
the region several times by simply hitting TAB several times.

The command usually bound to TAB is really meant for programming
languages, where it indents to "The Correct Indentation", so repeating
it makes no sense.

We could make it repeatable in text-mode buffers, but I suspect that
you'd also want to be able to "fine-tune" it or to un-indent in
a similar way, so maybe you want a more comprehensive solution.

I see.  I don't program but it's the same in org-mode.

If there is no spacial structure (programming, lists, outlines)
simply indenting as often as TAB is pressed seems very natural to
me. 


Thanks again, Gregor

And besides this -- in buffers where it does make sense, it's easy
enough to reactivate the region (with `C-x C-x C-x C-x' or the like) and
then TAB again.

So I don't think it's worth it to establish more functionality for
TAB/region things, and I'm closing this bug report.
