681: Cursor/Keypad Support
682:
683: Sadly Cursor/Keypad support is less straightforward than it should be.
684:
685: The various terminal emulators/consoles choose to differentiate the
686: cursor and keypad keys (with modifiers) in different ways (if at all!).
687: Furthermore they use different code set sequences for each key only
688: a subset of which the various curses libraries recognize. Partly due
689: to incomplete termcap/terminfo entries and partly due to inherent
690: limitations of those terminal capability databases.
691:
692: I give curses first crack at decoding the sequences. If it fails to decode
693: it we check for common ESC-prefixed sequences.
694:
695: All cursor/keypad results are translated into standard rogue movement
696: commands.
697:
698: Unmodified keys are translated to walk commands: hjklyubn
699: Modified (shift,control,alt) are translated to run commands: HJKLYUBN
