I’ll hazard a guess that they bind an event listener that fires when a key is pressed. If F and Ctrl are pressed (see
charCode,keyCode, andctrlKey) then they canevent.preventDefault()— preventing the browser-default “Find” interface — and instead render their own in-browser “Find” UI.Of course, this wouldn’t be fun without the usual hodgepodge of browser inconsistencies. That means if you’re taking the (strongly not recommended) no-library route, you might want to read up on the differences on Quirksmode.
