To get into shoot mode, start camera by pressing and holding on/off button until you see the logo.
Or, allow it to boot into play mode (press on/off, or play) and then 'half-press' shutter.
For CHDK menu, press Direct Print/Shortcut button ( <Alt> appears @bottom center screen ) and
then 'MENU'
hope that helps [edit: ...and welcome to the forum],
