Clickity is a tray-icon program to simulate mouse clicks and drags that are hard to perform because of limited hand use or limited pointing hardware. It runs on any X system with tray icons, as well as Microsoft Windows, and doesn't require an integrated desktop environment or accessiblity framework to be installed. Clickity can be activated by holding and then releasing the left mouse button or by moving the pointer and letting it dwell in position. Actions include single clicks, double clicks, and drags of the left, right, and middle buttons, as well as scroll wheel motion.
