Key press triggers help

Hello,

I have been trying to use the Control key as my trigger because I am creating a simulation of our system. But Storyline 360 won't take it unless it is paired with another key. Which is not what I want. Is there a way around that? Please help.

    The Ctrl, Shift, and Alt keys are designed as modifier keys. These special keys, when pressed in combination with other keys, trigger specific actions. The only way to detect when the Ctrl key is pressed on its own (without other modifiers) is to use JavaScript. You can write a script that listens for the Ctrl key press event, and when detected, it changes a variable value to true. Once the variable changes, you can trigger an action, such as jumping to the next slide.

  • Hi IngridCarrer168 I think they might avoid that due to potential conflict with other system and accessibility tool shortcuts. There could be another reason, just a theory. 

    Here's the JavaScript to do what you want. Just add this to the timeline start trigger.

    document.addEventListener("keydown", function(event) {
        if (event.ctrlKey) {
            const player = GetPlayer();
            const current = player.GetVar("ctrlkey") !== true;
            // forcing the "ctrlkey" value to change everytime the CTRL key is selected
            player.SetVar("ctrlkey",current);
        }
    });

    Attached is an example of implementation that just triggers an animation every time the CTRL key is selected.
