What do the different controls on the puzzle editor do?
Under the board there are seven square buttons. The first one, showing a blank puzzle, will erase you entire puzzle. The next two that look like paint pots can be used to fill in areas of the puzzle. The shaded one fills with the currently selected color, and the white one fills with white. After you click on the paint pot, you can then click on the screen, and all squares in the clicked on region will be changed to the new color. Normally the region fill function turns off after you do one fill. If you want to do multiple fills, do the click on the board with the shift key held down, or with the right mouse button There are also four large arrows. Clicking on these will shift your image in the direction selected. The circular arrows are undo and redo buttons. Note that your undo history is not saved. If you leave the edit environment and come back, you won’t be able to undo any more. There are several differently colored blocks at the bottom of the page. You can click on one of these
