How do you use enter to stop a q-basic program?  Also, how do you use those
"Keyboard Scan Codes"?  Like if I wanted to end a program with the Ctrl key
how would I do that?  Thanks in advance.

You can stop a QBasic program with END or SYSTEM

And to end a program by pressing CONTROL, take a look at the following:
(Just remove the lines for the conditions you do not want to check for)

WHILE INKEY$ <> "q"
	DEF SEG = 0
	plop% = PEEK(&H417)
	plop2% = PEEK(&H418)
	IF (plop% AND 2) THEN PRINT "LEFT SHIFT PRESSED"
	IF (plop% AND 1) THEN PRINT "RIGHT SHIFT PRESSED"
	IF (plop% AND 4) THEN PRINT "CONTROL PRESSED"
	IF (plop% AND 8) THEN PRINT "ALT PRESSED"
	IF (plop2% AND 16) THEN PRINT "SCROLL LOCK PRESSED"
	IF (plop2% AND 128) THEN PRINT "INSERT PRESSED"
	IF (plop2% AND 32) THEN PRINT "NUMLOCK PRESSED"
	IF (plop2% AND 64) THEN PRINT "CAPS LOCK PRESSED"
WEND

There are a few things you can check as well, like telling the Left & Right
CTRL/ALT apart, and whether or not CAPSLOCK, NUMLOCK, SCROLLLOCK and INSERT
are turned on...
