+Left-clicking on an arrow will move the appropriate row or column in
+the direction indicated. Right-clicking will move it in the opposite

+Alternatively, use the cursor keys to move the position indicator
+around the edge of the grid, and use the return key to move the

(All the actions described in \k{common-actions} are also available.)
Clicking with the left mouse button rotates the group anticlockwise.
Clicking with the right button rotates it clockwise.
+You can also move an outline square around the grid with the cursor
+keys; the square is the size above (2\by\.2 by default, or larger).
+Pressing the return key or space bar will rotate the current square
+anticlockwise or clockwise respectively.

space with no peg and no hole is not available for moving at all: it
is an obstacle which you must work around.
+You can also use the cursor keys to move a position indicator around

+cursor key, will jump the peg in that direction (if that is a legal
+move).

+is not obvious if you're on a region's boundary, since it depends on the
+direction from which you approached the boundary). Pressing the return
+key starts a drag of that colour, as above, which you control with the
+cursor keys; pressing the return key again finishes the drag. The
+space bar can be used similarly to create a stippled region.
+Double-pressing the return key (without moving the cursor) will clear
+the region, as a drag from an empty region does: this is useful with
