Emacs remember text selection

Question

I decided that I was ready to try something new, after a few years of using gEdit for most of my coding needs, and try to learn using Emacs. I knew this would be difficult,

Answer 1

You can do this with something like the following:

(add-hook 'text-mode-hook (lambda ()
                            (set (make-local-variable 'indent-region-function)
                                 (lambda (s e)
                                   (indent-rigidly s e tab-width)))))

Then selecting a region and hitting TAB. will indent the region by a tab-width. You can then exchange point and mark with C-x C-x and hit TAB again to repeat.

I do, however, agree with the previous answers that suggest using indent-rigidly directly.
