The program is controlled by the mouse, keyboard, a toolbar, and options in the File menu. The man is moved using keyboard arrow keys and the mouse. Moves can be undone with the Backspace command or the undo button in the Toolbar.
The Toolbar can be used to: change map sets, change maps, undo moves, redo moves, restart a map, show an animation of your moves so far, show an animation of a good solution, stop an animation. Use the left mouse button. The middle mouse button pops up a reminder of the function of the key clicked.
Note that for the four buttons above the meaning of "next" and "previous" depends on the current Map selection mode. Depending on the selection mode, "next" map may mean next, or next unsolved, or next whose solution can be improved. Likewise for "previous".
Clicking on a Toolbar button with the middle mouse button will produce a pop-up to remind users of the function of the button. For example the figure below is the pop-up for the Stop animation button.
The man can be moved using the keyboard arrow keys. Alternatively, if there is a clear path, click the mouse at the position you want the man to move to, and he will go there. If he moves slowly enough you may notice that either the man is blind or drunk, or that I have not put much effort into finding the shortest path, as he often seems to stagger and take unnecessary detours. But, as far as I know, if there is a possible path, he always finds it. So, if you want to use the mininum number of moves, use the arrow keys! To undo a move use the keyboard Backspace key or the Toolbar undo button. To redo an undone move, use the redo button in the Toolbar.
