thank you again, your comment led me to the solution, this worked so far.

var try1 = true;
window.addEventListener("keydown",check,false);
function check(key) {
if (key.keyCode == "65" && try1 == true) {


c.beginPath();
c.moveTo(150,150);
c.lineTo(300,150);
c.strokeStyle ="red"; //use hex #code

c.stroke();
try1 = false;
}
