A more convenient graphical way to specify the slice is with @kbd{s
m} (@code{doc-view-set-slice-using-mouse}), where you use the mouse to
-select the slice.
-@c ??? How does this work?
+select the slice. Simply press and hold the left mouse button at the
+upper-left corner of the region you want to have in the slice, then
+move the mouse pointer to the lower-right corner and release the
+button.
The most convenient way is to set the optimal slice by using
BoundingBox information automatically determined from the document by
-typing @kbd{s b} (@code{doc-view-set-slice-using-mouse}).
+typing @kbd{s b} (@code{doc-view-set-slice-from-bounding-box}).
@findex doc-view-reset-slice
To cancel the selected slice, type @kbd{s r}
