Cryptonomicon by Neil Stephenson had a subplot where a main character used morse code on his keyboard, or some other layered encoding on top of the keyboard, to write software and communicate surreptitiously even while his screen was being recorded.

Came across that book just recently in one of those free book libraries, tell me, was it a good read?

Cryptonomicon is one of the best reads on the planet, it's famous.

It would be slighly more useful to have something that uses the microphone to detect when you physicially tap the laptop e.g. with your finger, it could be used to keep typing even with your laptop screen down, imagine a spy movie where the baddies close your laptop and put a gun against your head and you have to put your hands in the air, but you use your knee under the table to tap type "shred -vzn 0 /dev/xxx", poof, all data gone.

This reminds me of that section in the book Cryptonomicon, where our hero is programming on a laptop that he knows is being spied upon using Tempest and probably more, and is using clandestine input via morse code on the shift (?) key. I really enjoyed that book.

> on the shift (?) key. Disabling Windows accessibility features is an indication of anti-social behavior.

Laptops are not generally social objects. The notion makes me a bit nauseous actually.

Earlier quoted context omitted.

I think this is doable; and practice makes perfect. I can enter passcode on my apple watch with my nose. It’s the smaller apple watch model. Nose is quite big.

I do this to my watch and phone, most often when cuddling the wife because one of my arms will doubtlessly be unavailable.

The nose as a pointing device ...

Gotta go find me a scientific study on that :)
