KEYBOARD Invoke the keyboard as if it were a Script-file.
	KEYBOARD invokes the keyboard as if it were a Script-file.
 	When placed in an M-file, KEYBOARD stops execution of the
 	file and gives control to the user's keyboard. The special 
 	status is indicated by a double prompt. Variables may be 
 	examined or changed - all MATLAB commands are valid. The 
 	keyboard mode is terminated by executing the command RETURN
 	(i.e. typing the six letters R-E-T-U-R-N and pressing the
 	return key).  Control returns to the invoking M-file.
