\\X - set mode X until other mode change sequence \X - set mode X for next character onlywhere X can be any of the following values and causes the following actions :
N - Switch to current default character set 1 - Switch to Simplex character set 2 - Switch to Duplex character set R - Roman font G - Greek font S - Script font I - Toggle italics U - Increase superscript/subscript level (move Up) D - Decrease superscript/subscript level (move Down) B - Backspace over previous characterSuperscript and subscripts are handled using a ``level'' philosophy. U increases the level by 1, D decreases it by 1 and the size of the characters is (0.7)**ABS(level) times the current defined size. The italic mode is toggled by the I escape code. The character size is defined using command SET CHARACTER.
