.APPENDIX Special printer support
A number of features have been added to support special printers.
Some of these require that the printer respond to specific special
code sequences or escape sequences.
The defaults are set by modifying RNPRE.MAC and enabling the default
symbols.  Some RNO files are supplied for various printers.

.le;  _^_> Causes the text to be shifted up 1/2 space for writing
superscripts, or cancelling subscripts.
.le; _^_< Shifts the text down 1/2 space for writing subsripts or cancelling
superscripts
This escape sequence conflicts with the CAPITALIZE FLAG if
the flag is enabled.  If the flag is enabled, it takes precedence over the
escape sequence definition.
.le;_< or _> will cause subscripts/superscripts if _.FLAGS#SPECIAL#_<_> is
used.
