  hjklyubn go one step in that direction
  HJKLYUBN run in that direction (until you hit a wall or a monster)
  g(dir) run in that direction until something interesting is seen
  G(dir) run in that direction until something interesting is seen (but not a corridor branch)
  m(dir) go one step in that direction (but don't pick up or touch objects)

In Rogue, use ctrl+direction to run until something interesting is seen. shift+direction still works to run until you hit something.
