VirtualKeyboard is an on-screen keyboard that offers point-and-click typing using pointing devices such as a head pointer, mouse, graphic tablet, trackball, etc. This program is designed primarily for disabled person but it can be used also to teach the children to write, to prepare kiosk environments, etc.
To use VirtualKeyboard simply click on the keys of the on-screen keyboard and each keypress will be sent to the active application. It works seamlessly with all standard Mac applications allowing you to type virtually anywhere a hardware keyboard can be used. As with a real keyboard, to get uppercase characters you click Shift first, or to type in all uppercase, click Lock. Similarly, it handles command-key combinations, dead-keys, and modifier key - click combinations.
