Sure; assuming M-x shell, i.e. buffer *shell*
Use a few commands  ('ls', 'pwd', 'cd ..' etc)
Now type C-c C-p at least once: This moves 'point' to one of the
previous input lines;
now  C-c RET  doesn't do anything in emacs 22, but it did what I
have used it for, in Emacs <= 21.x ,
namely 
- copies the input line to the end of your *shell* buffer
- moves 'point' (and scrolls if necessary) at the *end* of this line

such that another <return> simply would submit this line as a
new line of input.  The practical use is that I often slightly
change the line before resubmitting.

Is that sufficient?
