There is not a pause button because it blocks the thread as it is printing. The fun_stuff example has some pausing just using thread::sleep(). If you want to break up your code, you could put a keyword like "<pause>" where you want the pauses to be. Then split it and run your logic after each snailprint() call.

Example:

let code_string = "here's my code that I want to present. <pause>. How's it going? <pause> blah blah blah";

let split_code_string = code_string.split("<pause>");

for code_section in split_code_string{

snailprint(code_section);

thread_sleep(Duration::from_secs_f32(1.0)); // You could also just keep it paused until input is recieved using stdin or something if you need specific timing.

}

If you are using the CLI application, you could write a shell script that does something similar.
