! 746: Cursor/Keypad Support
! 747:
! 748: Sadly Cursor/Keypad support is less straightforward than it should be.
! 749:
! 750: The various terminal emulators/consoles choose to differentiate the
! 751: cursor and keypad keys (with modifiers) in different ways (if at all!).
! 752: Furthermore they use different code set sequences for each key only
! 753: a subset of which the various curses libraries recognize. Partly due
! 754: to incomplete termcap/terminfo entries and partly due to inherent
! 755: limitations of those terminal capability databases.
! 756:
! 757: I give curses first crack at decoding the sequences. If it fails to decode
! 758: it we check for common ESC-prefixed sequences.
! 759:
! 760: All cursor/keypad results are translated into standard rogue movement
! 761: commands.
! 762:
! 763: Unmodified keys are translated to walk commands: hjklyubn
