[c256]

When I’m trying to understand code, my hands are absolutely on the keyboard. This is very common and quite efficient once you learn how to navigate using a code editor.

This is similar to the way a mathematician will often ‘read’ math with a pencil and paper, or a musician will ‘read’ music with an instrument in hand.

When I’m reading prose, I often don’t have either a keyboard or a mouse, but that’s a very different operation (uses different parts of the brain, etc).
