I wrote a frontend for CompuServe's British Legends using Crosstalk Mk.4's scripting language CASL. It had a complete dungeon map and let me navigate using the PC's numeric keypad for directions. An onscreen keymap with labels for each number key showed where pressing that key would lead. It even randomized choices, so if NW and W both led to the same place it would pick one randomly if you hit either key. (This was to confuse wizards who could tell who you were by your habitual choices.)
