H Everyone,

In the code below, when a key is pressed, a new .txt file is loaded. My question is, how could I introduce added functionality whereby the new file is loaded after 5 seconds, say, even if no key has been pressed? To clarify, a new .txt is loaded after key press, but is loaded in any case after 5 seconds...
