test:keystroke

• (test:keystroke key modifier-list) -> void
      key : (union char symbol)
      modifier-list = null : (listof (union 'alt 'control 'meta 'shift 'noalt 'nocontrol 'nometa 'noshift))

  This function simulates a user pressing a key. The argument, key, is just like the argument to the get-key-code method of the key-event% class.

  Note: To send the ``Enter'' key, use #\return, not #\newline.

  The 'shift or 'noshift modifier is implicitly set from key, but is overridden by the argument list. The 'shift modifier is set for any capitol alpha-numeric letters and any of the characters returned by keys:get-shifted-key-list.

  If conflicting modifiers are provided, the ones later in the list are used.
