This is a well-known browser security technique. In JavaScript, calling .toString() on a native browser function returns "function appendBuffer() { [native code] }". Calling it on a JavaScript function returns the actual source code. So if your appendBuffer has been monkey-patched, .toString() will betray you; it’ll return the attacker’s JavaScript source instead of the expected native code string.

I got resin-printed key covers to replace the top row of unused switch slots and a set of KLP Lamé keycaps from 3dkeycap to give a sculpted profile to the remaining keys. They are blanks in a solid grey color that lets the keyboard LEDs shine through.

My Voyager has clicky Kailh Choc White keyswitches.
