Shift a region or line in emacs

Question

I\'m looking for a way in emacs to shift text to the right or to the left by n spaces. A similar functionality that it in vim << or >>

Answer 1

To achieve this I usually do a trick:

• activate CUA mode
• go to the beginning of line
• C-RET, now if you move the cursor you should see a rectangular red region
• Move the cursor down the lines and type space until you've obtained the correct shifting.

This can be done also programmatically in some way (in the same way).

EDIT: I've just read the article in emacs wiki, it's the same solution except for the CUA mode that is infinitely more powerful than the "common" rectanguar selection (since it's visual).
