There are some other characters that can be printed for special functions, although they are not easily available from the keyboard. In order to get these into quotes, you must leave empty spaces for them in the line, press <RETURN>, and go back to edit the line. Now you hold down the <CTRL> (ConTRoL) key and type <RVS ON> (ReVerSe-ON) to start typing reversed characters. Type the keys as shown below:

Key Function	Key Entered	Appearance
Shifted RETURN	<SHIFT+M>
Switch to upper/lower case	<N>
Switch to upper/graphics	<SHIFT+N>

Holding down the <SHIFT> key and hitting <RETURN> causes a carriage-return and line-feed on the screen but does not end the string. This works with LIST as well as PRINT, so editing will be almost impossible if this character is used. When output is switched to the printer via the CMD statement, the reverse "N" character shifts the printer into its upper-lower case character set and the <SHIFT> "N" shifts the printer into the upper-case/graphics character set.

Reverse video characters can be included in strings by holding down the ConTRoL <CTRL> key and pressing ReVerSe <RVS>, causing a reversed R to appear inside the quotes. This will make all characters print in reverse video (like a negative of a photograph). To end the reverse printing, press <CTRL> and <RVS OFF> (ReVerSe OFF) by holding down the <CTRL> key and typing the <RVS OFF> key, which prints a reverse R. Numeric data can be printed in reverse video by first printing a CHR$(18). Printing a CHR$(146) or a carriage-return will cancel reverse video output.
