! 798: Cursor/Keypad Support
! 799:
! 800: Sadly Cursor/Keypad support is less straightforward than it should be.
! 801:
! 802: The various terminal emulators/consoles choose to differentiate the
! 803: cursor and keypad keys (with modifiers) in different ways (if at all!).
! 804: Furthermore they use different code set sequences for each key only
! 805: a subset of which the various curses libraries recognize. Partly due
! 806: to incomplete termcap/terminfo entries and partly due to inherent
! 807: limitations of those terminal capability databases.
! 808:
! 809: I give curses first crack at decoding the sequences. If it fails to decode
! 810: it we check for common ESC-prefixed sequences.
! 811:
! 812: All cursor/keypad results are translated into standard rogue movement
! 813: commands.
! 814:
! 815: Unmodified keys are translated to walk commands: hjklyubn
