Floating Screen Keyboard

[Peter Reid]

I'm trying to create a floating screen keyboard application that will  
allow me to use a mouse to "type" into other applications by clicking  
on the keys in the floating keyboard.  I'm trying to do this on a Mac  
under OS X 10.4.x using Rev 2.8.1.

For example, if I'm using a web browser on a projected image, I might  
be using a mouse only and want to be able to type into the browser  
URL address box.  I have looked a the built-in OS X keyboard viewer  
and it is too small, can't be resized and you can't use it to type in  
capital letters!  This is why I thought I'd see if I could make an  
app in Rev that presented a scalable floating keyboard for mouse  
entry of text.

However, I can't see how I can send individual characters to whatever  
is the currently active window as if they had been typed on the real  
keyboard.

Any suggestions please?
