1036  * can enter "location" mode, and use the direction keys to move one

1038  * only target a monster (as opposed to a location) if the monster is
1039  * target_able and the "interesting" mode is being used.
1040  *
1041  * The current grid is described using the "look" method above, and
1042  * a new command may be entered at any time, but note that if the
