684: Cursor/Keypad Support
685:
686: Sadly Cursor/Keypad support is less straightforward than it should be.
687:
688: The various terminal emulators/consoles choose to differentiate the
689: cursor and keypad keys (with modifiers) in different ways (if at all!).
690: Furthermore they use different code set sequences for each key only
691: a subset of which the various curses libraries recognize. Partly due
692: to incomplete termcap/terminfo entries and partly due to inherent
693: limitations of those terminal capability databases.
694:
695: I give curses first crack at decoding the sequences. If it fails to decode
696: it we check for common ESC-prefixed sequences.
697:
698: All cursor/keypad results are translated into standard rogue movement
699: commands.
700:
701: Unmodified keys are translated to walk commands: hjklyubn
702: Modified (shift,control,alt) are translated to run commands: HJKLYUBN
