While "Catch Flies!" is toggled on, the up arrow key is held down causing the turtle to move forward. The left arrow key turns the turtle to the left as long as the button is held. Take note that the frog only moves while the key is held down.

Notes​

An important difference between Key Held? and Key Typed? is that Key Typed? returns true only on ticks when the specific key is held AND when it was not held on the previous tick.

Basically, Key Typed? returns true only on the tick when the button is first pushed and not on consecutive ticks. Key Held? returns true forever as long as the specific key is being held down.

  • Key Typed? - Returns true only when a key is first pressed
