These pages are the same in the program and on the web. In the program,
/manual opens them from a copy kept beside Heckers Sketch, so
they are there without the internet once it has downloaded them.
Click any picture or animation to see it larger - in its own window in the program, or a new tab on the web.
Light or dark. The button at the top of every page switches between them, on the web and in the program alike: Auto follows whatever your phone, desktop or - inside the program - the program itself is set to, and Light and Dark say so regardless. The choice is remembered.
Every picture is taken on an empty sheet by driving the program itself, with the smallest thing that shows the tool.
