How do I make temporary text?

Nautilus

How can I make a temporary text, like you press a key, the text shows for a few seconds, and then it disappears. And how do I use variables in text (I don't know if it's the right way to say that), for example, in C it's like this:

printf("Hello, %s", variable_name);

Or instead of %s it can be a number: %d. Any help is appreciated.

if you press a key, the text shows for some number of milliseconds, then disappears when the clock has changed that much.

int duration = 1000;
int pressTime;

In draw:

if( millis() > pressTime + duration ) {
  text("foo", 0, 0);
}

And:

void keyReleased() {
  pressTime = millis();
}

Chrisir

println("Hello " +  s + variable_name);

and

fill(255,0,0); 
text("Hello " +  s + variable_name, 44, 120);
