| 822 Cursor/Keypad Support | |
| 823 | |
| 824 Sadly Cursor/Keypad support is less straightforward than it should be. | |
| 825 | |
| 826 The various terminal emulators/consoles choose to differentiate the | |
| 827 cursor and keypad keys (with modifiers) in different ways (if at all!). | |
| 828 Furthermore they use different code set sequences for each key only | |
| 829 a subset of which the various curses libraries recognize. Partly due | |
| 830 to incomplete termcap/terminfo entries and partly due to inherent | |
| 831 limitations of those terminal capability databases. | |
| 832 | |
| 833 I give curses first crack at decoding the sequences. If it fails to decode | |
| 834 it we check for common ESC-prefixed sequences. | |
| 835 | |
| 836 All cursor/keypad results are translated into standard rogue movement | |
| 837 commands. | |
| 838 | |
| 839 Unmodified keys are translated to walk commands: hjklyubn | |
| 840 Modified (shift,control,alt) are translated to run commands: HJKLYUBN | |
