"Walking" Layout

[ben]

I've written some code here: https://github.com/ben-horner/twiddler_layout/ to try optimizing the layout.

The idea is that held buttons don't count, and if you release only one button, and press one button, that it should be as easy a transition as two single key presses (almost). This gives you many more chords available at this simplest level of difficulty (single key equivalent).

I think of moving between two-key chords only changing one key, as "walking" the keyboard. The layout I have posted there achieves this for slightly over 65% of transitions.

Here is a cheat sheet for the layout, to give you an idea what it's actually like:
(capitol L, M, and R represents the held key that a box has in common)

L		  M		    R
b s q		e   l		v i x
j w u		d a r		k c f
+ ( {		* . !		& ) }

b e v		s   i		q l x	
L		  M		    R	
g h m		n t o		z y p	
- [ $		/ ? '		| ] ;	

j d k		w a c		u r f	
g n z		h t y		m o p	
L		  M		    R	
= < #		% , "		^ > @	

+ * &		( . )		{ ! }	
- / |		[ ? ]		$ ' ;	
= % ^		< , >		# " @	
L		  M		    R

Very interesting approach!
