(char 1) ;; => \^A Seems to be the character literal captured by libGDX's keyTyped callback (class: InputProcessor), when I press Ctrl+a. But is there any way to type these literals in Clojure, so I don't have to compare against magic values like 1?

\u0001, still magic, but at least a literal. Libgdx should be able to capture ctrl and A keypresses separately, which might make more sense if you are writing a game.

Yes, I went with handling the keyDown/`keyUp` events instead, which lets me get the keys separately.

@curlyfry That doesn't mention \^A though?

Ah, I see. Haven't come across it before, sorry

alexmiller14:06:32

that’s a Unicode char literal

user=> (= (char 1) \u0001)

@alexmiller Ah, I see thanks!
