  22. * \brief Source: additional keyboard support routines
  23. *
  24. * PURPOSE:
  25. * We would like to support the direct ALT-?/META-? and some other 'extra'
  26. * keyboard functionality provided by some terminals under some OSes (and
  27. * not supported by the 'learn keys...' facility of 'mc'.
  28. * (First target platform: QNX.)
  29. *
  30. * REMARK:
  31. *
  32. * Implementation strategy: we don't want to rely on a specific terminal
  33. * information database management API (termcap,terminfo,SLang,...), so we
  34. * try to define a superset of the possible key identifiers here.
