31 * \brief Source: additional keyboard support routines
32 *
33 * PURPOSE:
34 * We would like to support the direct ALT-?/META-? and some other 'extra'
35 * keyboard functionality provided by some terminals under some OSes (and
36 * not supported by the 'learn keys...' facility of 'mc'.
37 * (First target platform: QNX.)
38 *
39 * REMARK:
40 *
41 * Implementation strategy: we don't want to rely on a specific terminal
42 * information database management API (termcap,terminfo,SLang,...), so we
43 * try to define a superset of the possible key identifiers here.
44 *
