Indent region by one tabstop

Indent region by one tabstop

[BDB]

Is there a way to make emacs move a region of code left or right by one
tabstop?  I don't want to use emacs' built in indentation because it's
not indenting the lines where I want them to be.

Use `indent-rigidly' with the value of `tab-width'?

(defun my-indent-a-tab-width (start end)
  (interactive "r")
  (indent-rigidly start end tab-width))

Works great, thanks!  You wouldn't happen to know a way to do the inverse,
delete 4 spaces from the beginning of each line in a region?

Same function, `indent-rigidly', but with a negative argument.

C-h f indent-rigidly

You can also try

C-h K C-x r o
C-h K C-x r k

Btw, it takes some time to get used to rectangle editing.

Here's my proposed improvement:

what about binding that at `indent-tabs-mode'?

Since my "tl-indent-region" supersedes "indent-rigidly" I just bind it
globally to "C-x TAB". Technically it has all the features of
"indent-rigidly".

But you could add your suggestion to the bug report (#8196).

yes, will do that.

BTW I'm concerned it the default just changes, bug-reports resp. feature requests will drop in from the other side than.

You might want to take a look at replace-rectangle. For example, mark a region
from in the first column of the first lane to the first column of the last line.
Then, using replace-rectangle, insert a tab.
