I used to be a specialized keyboard fanatic. Ultimately, what cured me of this "need" was learning how to type in braille code, which uses 8 keys plus a spacebar. Thanks to accessibility advancements, and especially on mobile devices, I can carry around a mini braille display and efficiently control everything I could ever imagine to need, without specialized keys. But, it requires learning a certain combination of keys (as in commands) to do what you want. I can also efficiently take notes in very advanced math using a braille display plus a Raspberry Pi (see: http://liblouis.org/ http://liblouis.org/), that none of my friends can do efficiently, digitally. There is a really cool braille notetaker that is integrated with Android, that allows for taking notes in various braille codes (such as for math), but it is obscenely expensive, and is not as well supported as the liblouis package.

For the sighted (I am sighted, although I have a functional visual impairment which affects my ability to read standard text), probably the way to go is to use a BraillePen: http://braillepen.com/braillepens/ http://braillepen.com/braillepens/ You do need an actual refreshable braille display to do this without audio feedback (via headphones in public). Usually you have to make a compromise between the amount of braille cells and portability. My usual go to device is the HIMS Braille Edge 40. On the go, I use a Handy Tech Actilino, which has 16 cells and is ergonomic and has an auto-scroll reading feature.
