It is a user option, IOW a variable that you can customize.  It is not a
function, let alone a command (so you cannot invoke it using `M-x').

Use `C-h v echo-keystrokes' to see its doc.

However, the doc string is incomplete - see this bug report:
http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10503.  For more complete info, see
the Emacs or Elisp manual: use `i echo-keystrokes' in the manual.

The way to make `echo-keystrokes' take effect or not is to use `M-x
customize-option' or `M-x set-variable'.

Those look like keyboard keys to me, not mouse events.  If you use the mouse
(e.g. click `mouse-1' somewhere, then click `mouse-3' somewhere, to select some
text) you should see mouse events such as I show above.
