Earlier quoted context omitted.
That's why you should also choose a small keyboard, like one with 34 keys or similar.
What type of layout do you use for 34 keys? I've got a 42 key split board so I'm not a total noob to minimalist keyboard but struggle to see how 34 keys can be used effectively.
In reality it would be easy to go down to a single thumb key, making it 32 keys.
In short I have layers for numbers and symbols, I make heavy use of combos (pressing multiple keys at once) where I have modifiers, big keys like escape and enter and also the numbers and symbols (for typing singletons). I also have different functions for long press and I use capsword and numword (caps lock / layer that turns off intelligently).
