One of the problems recurring in most different layouts is that they almost always use a regular keyboard design. Horizontally staggered and 6 keys per index finger, while leaving all the real estate that's occupied with ,.;'/[ alone. Especially the 6 key index finger problem is a tough one... everyone seems to be doing it and for the keyboard design I have in mind it's not applicable. But maybe his program is customizable. I'll have a look

Are you saying the index fingers should handle more than 6 keys, and/or be ortholinear?

no! yes! ideally we'd get rid of two letters in the alphabet (Q and C) and give all fingers 3 keys. But as that's maybe somewhat too radical, so we have to compromise and give the index fingers 4 keys. Ortholinear? definitely not staggered horizontally, but this 4th key might be best placed to the side.

By my count, on a standard ANSI keyboard, the right pinky has 13 keys (10 character keys), and the left 8 (5 character keys and tab), not counting the bottom row of modifiers. The middle and ring fingers each have 4 keys, counting the number row, and the index fingers 8.

I wonder why the thumbs only have the space bar. Perhaps a row under the space bar with the most common punctuation would be a good way to take some of the load off of the more overused fingers.
