713: Cursor/Keypad Support
714:
715: Sadly Cursor/Keypad support is less straightforward than it should be.
716:
717: The various terminal emulators/consoles choose to differentiate the
718: cursor and keypad keys (with modifiers) in different ways (if at all!).
719: Furthermore they use different code set sequences for each key only
720: a subset of which the various curses libraries recognize. Partly due
721: to incomplete termcap/terminfo entries and partly due to inherent
722: limitations of those terminal capability databases.
723:
724: I give curses first crack at decoding the sequences. If it fails to decode
725: it we check for common ESC-prefixed sequences.
726:
727: All cursor/keypad results are translated into standard rogue movement
728: commands.
729:
730: Unmodified keys are translated to walk commands: hjklyubn
731: Modified (shift,control,alt) are translated to run commands: HJKLYUBN
