 Usage
 -----
 
-``probe``
-    Displays properties of the tile selected with :kbd:`k`. Some of these
-    properties can be passed into `tiletypes`.
+``probe [<options>]``
+    Displays properties of the tile highlighted with the keyboard cursor or at
+    the specified coordinates. If you do not have a keyboard cursor visible,
+    enter a mode that shows the keyboard cursor (like mining mode). If the
+    keyboard cursor is still not visible, hit Alt-k to invoke
+    `toggle-kbd-cursor`.
 ``bprobe``
-    Displays properties of the building selected with :kbd:`q` or :kbd:`t`.
-    For deeper inspection of the building, see `gui/gm-editor`.
+    Displays properties of the selected building. For deeper inspection of the
+    building, see `gui/gm-editor`.
 ``cprobe``
-    Displays properties of the unit selected with :kbd:`v`. It also displays the
-    IDs of any worn items. For deeper inspection of the unit and inventory items,
-    see `gui/gm-unit` and `gui/gm-editor`.

+    necessary.
