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
764: Modified (shift,control,alt) are translated to run commands: HJKLYUBN
