How to write comma character in a SLIME EMACS window

Question

How can I write a "," (comma) character in the SLIME emacs window? The , key brings up the SLIME command prompt automatically.

Thanks, a Lisp beginner

You can insert , by C-q, (Control-q and then comma). C-q is bound to quoted-insert, which can be generally used whenever you want Emacs to read a next input character and insert it instead of invoking a command bound to the input character.
