Back in the 1.3 days there was a shareware program called Oskey. I think it was on a Fish Disk orignally but I'm switched if I can find it.
It let you click on icons to form keypresses, and you could then copy and paste the text when a key was defective (or no keyboard was attached, which made it VERY useful).
Anyone remember this or give me a pointer to where I can find it? It worked on 1.3 and 3.0, so should work with just about any classic Amiga.
