Ideas:
For standard or split keyboards.
Left or right hand.
Shift with thumb or locked for one key.
Layers--one or two.
Numbers or no.

Suggestions:
  • space should be part of letters
  • omit rows 0 and 4
  • need more layers
  • thumbs only move between layers

Multi-layers for One-handed layout

Ten main keys: home block and inward index. Thumb for layer switching, and pinky for Enter and Tab.

Below layout matches the right hand.

Code: [Select]
Layer 0:
  nra
 st e
  hio

Layer 1:
  gdp
 yulc
  wmf

Layer 2:
  v,x
 jk.b
  zq'


Layer 0 is base layer without modifiers. Layer 1 could be accessed by Caps Lock. Layer 2 could be accessed by AltGr. Uppercase requires Shift in down position; can also try macro to capitalize the previous word.

Typing a letter should automatically revert back to Layer 0.

Num Lock unlocks numbers and puncs (not shown here).

If other hand is able, even staying at home keys to press modifiers would provides access to at least six layers. Base layer is unmodfied, then each offhand finger at home is another layer individually; if simultaneous modifiers is achievable, that's exponentially more layers.
