I am using emacs 2.2 at work and 2.3 at home for python coding. I want to
know how can I indent or outdent a block of code multiple times. When I mean
is when I select a code part using C-space and then use C-x <tab> / C-c-> /
C-c-< to indent or outdent, this only works once and then deselect the
block. What if i want to indent multiple times on the same code block do I
have to repeated this key sequence from selecting the block to indent.

No, the region has not been deselected. All that has happened is that
the "active" flag has been cleared. The indent/outdent functions ignore
the "active" flag.

You might try the "C-x z" command, which means "repeat previous
command".

Commit message of latest revision of python-mode.el (note: not
python.el) says:
"When shifting regions right and left, keep the region active in Emacs."
This might solve your problem.
Get it at

or with
bzr branch lp:python-mode

How do you reactivate the region.

Exchanging point and mark (C-x C-x, by default) will reactivate the
region. However, unless you are invoking a function that behaves
differently depending on whether the region is active or not, you
generally don't have to do this. For instance, in your previous query
about repeatedly in/outdenting the region, it doesn't matter whether the
region is "active" -- it will still get in/outdented.
[I'm beginning to think it was a mistake to turn on transient mark mode
by default; it seems to be generating more confusion than it is worth.]

Someone please comment on that final sentence, re transient-mark-mode.
Thanks!

Hmmm. Nice, I guess. First I've heard of it.
So I guess I should include this for possible elaboration?
C-x z runs the command repeat
which is an interactive autoloaded Lisp function in `repeat'.
It is bound to C-x z.
(repeat repeat-arg)
Repeat most recently executed command.
With prefix arg, apply new prefix arg to that command; otherwise, use
the prefix arg that was used before (if any).
This command is like the `.' command in the vi editor.
If this command is invoked by a multi-character key sequence, it can then
be repeated by repeating the final character of that sequence. This behavior
can be modified by the global variable `repeat-on-final-keystroke'.
C-x ESC ESC (translated from C-x <escape> <escape>) runs the command repeat-complex-command
which is an interactive compiled Lisp function in `simple.el'.
It is bound to <redo>, <again>, C-x M-ESC, C-x M-:.
(repeat-complex-command arg)
Edit and re-evaluate last complex command, or argth from last.
A complex command is one which used the minibuffer.
The command is placed in the minibuffer as a Lisp form for editing.
The result is executed, repeating the command as changed.
If the command has been changed or is not the most recent previous command
it is added to the front of the command history.
You can use the minibuffer history commands M-n and M-p
to get different commands to edit and resubmit.
Thanks,
David
PS: Maybe someone could send a msg to rms to make sure that these two
appear together in the manual?
