Name

keyTyped()

Examples
// Run this program to learn how each of these functions
// relate to the others.

void draw() { } // Empty draw() needed to keep the program running

void keyPressed() {
  println("pressed " + int(key) + " " + keyCode);
}

void keyTyped() {
  println("typed " + int(key) + " " + keyCode);
}

void keyReleased() {
  println("released " + int(key) + " " + keyCode);
}

Description The keyTyped() function is called once every time a key is pressed, but action keys such as Ctrl, Shift, and Alt are ignored. Because of how operating systems handle key repeats, holding down a key will cause multiple calls to keyTyped(), the rate is set by the operating system and how each computer is configured.
JavaScript
Notes
With the "@pjs globalKeyEvents" directive you can catch all key events on the window your sketch is running in. You can set it with the "Playback Settings" tool in the "JavaScript" menu.
