key on a Macintosh and runs the handler
updateData if the key was pressed:
-- Lingo syntax
if (_key.keyPressed(RETURN)) then
updateData
end if
// JavaScript syntax
if (_key.keyPressed(36)) {

put("The key is down")
end if
// JavaScript syntax
if (_key.keyPressed(0)) {
put("The key is down");
}
This statement uses the ASCII strings to test if the a and b keys are down and displays the result
in the Message window:

if (_key.keyPressed("a") and _key.keyPressed("b")) then
put("Both keys are down")
end if
// JavaScript syntax
