newRPL keyboard overlay

[Claudio L.]

Wow! This is extraordinary work!!
I mean the convincing your wife part, the other part only takes skill but proper wife management is truly a hidden art. Bravo!

My suggestions:
a) Some keys have important functionality in the Shift-Hold plane. Perhaps you could prefix the label with the symbols U+21B0 (↰) and U+21B1 (↱) to indicate shift-hold.

b)There's some space around the cursor keys to show their additional functionality (very common use once you know they are there):
* HOME and UPDIR to the UP cursor as left-shift-hold+UP and left-shift+UP respectively.
* Begin/End to the left/right cursors as left-shifted key
* Copy and Paste to left/right cursors as shift-hold
* Cut to down cursor as shift-hold
* UNDO to the left cursor key (no shift, but only valid on the stack, not sure which color you would use here)

c)The On-hold plane has a lot of functionality in newRPL as well, my suggestion is to make the On key label a different color, then add matching colored labels to certain keys with that functionality:
* On+UP/DOWN = Increase/decrease system precision
* On+Space = ENG/SCI/FIX
* On+Numbers = # of significant digits for display
* On+. = Cycle through using dot or comma as decimal/thousand separators.
* On+* and / = Move ENG display exponent by 3 places.
and of course On+plus/minus = contrast (a classic).

These above are just a few keys I use quite often and sometimes I forget which shift-plane they were, so a proper overlay would help.
