1284  * All locations must be on the current panel.  Consider the use of

1286  * some form of "scrolling" the map around the cursor.
1287  * That is, consider the possibility of "auto-scrolling" the screen
1288  * while the cursor moves around.  This may require changes in the
1289  * "update_monster()" code to allow "visibility" even if off panel, and
1290  * may require dynamic recalculation of the "temp" grid set.
1291  *
1292  * Hack -- targeting/observing an "outer border grid" may induce
1293  * problems, so this is not currently allowed.
1294  *
1295  * The player can use the direction keys to move among "interesting"
1296  * grids in a heuristic manner, or the "space", "+", and "-" keys to
1297  * move through the "interesting" grids in a sequential manner, or
1298  * can enter "location" mode, and use the direction keys to move one
1299  * grid at a time in any direction.  The "t" (set target) command will
1300  * only target a monster (as opposed to a location) if the monster is
1301  * target_able and the "interesting" mode is being used.
1302  *
1303  * The current grid is described using the "look" method above, and
1304  * a new command may be entered at any time, but note that if the
1305  * "TARGET_LOOK" bit flag is set (or if we are in "location" mode,
1306  * where "space" has no obvious meaning) then "space" will scan
1307  * through the description of the current grid until done, instead
1308  * of immediately jumping to the next "interesting" grid.  This
1309  * allows the "target" command to retain its old semantics.
1310  *
1311  * The "*", "+", and "-" keys may always be used to jump immediately
1312  * to the next (or previous) interesting grid, in the proper mode.
1313  *
1314  * The "return" key may always be used to scan through a complete
1315  * grid description (forever).
1316  *
