Unable to Un-indent with Emacs 24

Unable to Un-indent with Emacs 24

[Ari King]

Hi,

I've recently started using Emacs. Unfortunately, I'm unable to un-indent code blocks. If I select a block using C-space and then C-u -2 C-x TAB -- nothing happens. Does anyone now what could be wrong? Or how to find out?

The only substantive change I've made is installing technomancy's emacs starter kit (https://github.com/technomancy/emacs-starter-kit)

Thanks.

Try it with "emacs -Q" and if that works correctly, then try remove
things from your .emacs until you find the culprit.

Can't help you there (my suggestion is to not do that, but I'm
obviously biased).

You can also use kill rectangle for removing leading whitespace.  

    C-x r k

I tried "C-u -2 C-x TAB" with "emacs -Q", but got "This buffer cannot use imenu-default-create-index-function." Anyone know why I'm getting this message?

However, "C-x r k" did work. 

Thanks. Hope everyone enjoyed the holidays.

What is your Emacs version?  I don't see that using Emacs 24 or 23 or 22 or 21
or 20, on MS Windows.

What is an exact recipe - are you leaving anything out?
What is the buffer's mode?  Etc.

(BTW, you can just do `C- - 2' instead of `C-u - 2', and `C-2' instead of `C-u
2'.)

Emacs 24 on Ubuntu 12.10

"C-u -2 C-x TAB"
No, I didn't leave anything out.

Coffeescript mode

I believe the problem was the "C-x" (see above). If I do `C- - 2' or `C-u - 2', as suggested above, un-indenting works. Thanks for the heads-up.

Best,
