For ActivStudio software. Doo-dahs are a wonderful way to bring information into a classroom discussion in a controlled manner. A Doo-Dah can contain text, annotations or images, even those added or created on the fly. A picture is worth a thousand words, so download the file and have a play. You will soon learn the power of doodahs!
