PuTTY has a special mode for playing NetHack. You can enable it by selecting ‘NetHack’ in the ‘Initial state of numeric keypad’ control.
In this mode, the numeric keypad keys 1-9 generate the NetHack movement commands (hjklyubn
). The 5 key generates the .
command (do nothing).
In addition, pressing Shift or Ctrl with the keypad keys generate the Shift- or Ctrl-keys you would expect (e.g. keypad-7 generates ‘y
’, so Shift-keypad-7 generates ‘Y
’ and Ctrl-keypad-7 generates Ctrl-Y); these commands tell NetHack to keep moving you in the same direction until you encounter something interesting.
For some reason, this feature only works properly when Num Lock is on. We don't know why.
