In many pixel drawing tools it is possible to fix mistakes quickly by using the secondary mouse button. For example, the foreground color is applied with the primary button, while the secondary provides the background. In Petmate we have characters instead of pixels, so in order to "erase", the secondary button should apply a space character. However, if the secondary button/character could be freely chosen by user, it would also enable us to draw with two chars without jumping back and forth between the canvas and the character palette. Perhaps a secondary color assigned with the extra char could also be handy at sometimes.
