This is a good idea.
You could use the same principle to send 27 different values to a single RCX.
I.e. your one and only RCX could act as its own MUX.
Here's an encoding scheme that gives you 1 one-key combination, 3 two-key
combinations, and 6 3-key combinations. You pay a price for the shortcuts,
though. For 27 or more values you need at least 5 keystrokes. For values from 11
to 253 you need 7 keystrokes (and a good wetware trinary calculator)!
Value : key combination
1 : 1
2 : 2 1
3 : 2 2
4 : 2 3
5 : 3 1 1
6 : 3 1 2
7 : 3 1 3
8 : 3 2 1
9 : 3 2 2
10: 3 2 3
11-253: 3 3 n n n n n, where n is 1, 2 or 3

This is workable for us nerd couch potatoes who think in binary and are really fast with the (...) (23 years ago, 23-May-01, to lugnet.robotics)
