1008  * while the cursor moves around.  This may require changes in the
1009  * "update_monster()" code to allow "visibility" even if off panel, and

1013  * problems, so this is not currently allowed.

1017  * move through the "interesting" grids in a sequential manner, or
1018  * can enter "location" mode, and use the direction keys to move one
1019  * grid at a time in any direction.  The "t" (set target) command will
1020  * only target a monster (as opposed to a location) if the monster is
1021  * target_able and the "interesting" mode is being used.
1022  *
1023  * The current grid is described using the "look" method above, and
1024  * a new command may be entered at any time, but note that if the
1025  * "TARGET_LOOK" bit flag is set (or if we are in "location" mode,
1026  * where "space" has no obvious meaning) then "space" will scan
1027  * through the description of the current grid until done, instead
1028  * of immediately jumping to the next "interesting" grid.  This
