This probably has absolutely nothing to do with it, but there was a thing
sold in the UK called a 'Simplifier'. It connected between a PC and its
keyboard, and had a number of 'function keys' on the top and some LCD
displays to label them. There were cartridges for most major PC
applications, including Lotus 1-2-3 (I happen to have that cartridge).
When in use, the displays would provide appropriate labels for the keys
-- for example 'Enter new cell'. You'd then get another menu on the keys
with 'Enter number', 'Enter Text', 'Enter Formula', etc. When you pressed
one of those keys it would send the appropriate keycodes to the PC to
perform the desired action.

You could, of course, also use the normal PC keyboard if you wanted to.

Has anyone else ever come across this device?
