My solution doesn't simulate pressing `r' as such (which looks like it
will require some substantial setup), so I approached the test slightly

 - 1) Ensure =org-speed-command-default-hook= returns t when valid
       (default) speed command and bol
 - 2) Ensure actual speed command promotes correctly
 - 3) Use a test-buffer (with org-mode enabled) to avoid messing with
       test example

There may be a better solution however.

Best, Martyn
