/** \file keyxdef.c
* \brief Source: additional keyboard support routines
*
* 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.
*
