Emacs line indentation

Hi. I'm writing a document in Python, so indentation is crucial.

I want to indent a whole section by exactly one tab. Any idea how to go about this? I'm using terminal emacs (no mouse input)

Thanks for any help!

I guess Python is a little tricky because emacs cannot use the usual C-M-q to indent a code block since the indentation defines the block!
How about C-x TAB ( the indent-rigidly command) which shifts the selected region? The command takes an argument in the usual way to specify the number of spaces to move, e.g. C-u n C-x TAB to move the selected text n spaces. n can be negative to un-indent.

Great. Thank you. This actually only inserts a space, but I'm not complaining.
