=head2 Menus

=head3 File

The I<New> option allows the user to create a new board. Choose the width and height of the board and whether the initial cell status will be all 'dead', all 'live' or chosen at random according to a specified percentage chance. Use the I<Rules> subm...

=head3 Options

I<Play/Pause> starts and pauses the simulation. This can also be done from the space bar.

I<Grid> toggles the cell grid on and off.

I<Autogrow> toggles the 'autogrow' on and off. When activated, the size of the board will be enlarged if there are live cells close to the edge of the board.

I<Status line> toggles the status text which can be displayed along the bottom of the main window. This gives some information as to the current state of the simulation.

I<Snapshot board> will create a .png image file of the board in the current working directory.

I<Loop delay> presents a list of presets which affects the speed of the simulation. 

I<Rules> allows the user to select from a preset list of birth/survival rules, or use the I<Custom rule> dialog to specify one.

I<Zoom> opens the zoom dialog.

I<Live cell color> allows the user to select the color of a 'live' cell.

I<Dead cell color> allows the user to select the color of a 'dead' cell.

I<Grid color> allows the user to select the color of the grid.

I<Edit mode> can be used to switch in and out of 'edit mode'. When in edit mode clicking the left mouse button on the board will toggle the state of the cell under the cursor (indicated by a highlighted cell). Entering edit mode pauses the simulation...

=head3 About

Provides a small 'about' dialog.

=head2 Mouse interaction

Pressing the space bar will play and pause the simulation.

When paused, the ']' key will step the simulation.
