/*
 * PURPOSE:
 * 
 *   We would like to support the direct ALT-?/META-? and some other 'extra'
 *   keyboard functionality provided by some terminals under some OSes (and
 *   not supported by the 'learn keys...' facility of 'mc'.
 *   (First target platform: QNX.)
 * 
 * REMARK:
 * 
 *   Implementation strategy: we don't want to rely on a specific terminal
 *   information database management API (termcap,terminfo,SLang,...), so we
 *   try to define a superset of the possible key identifiers here.
