Double click and modifiers on SD

We don't have built in support for designing decks differently based on modifier keys, but you can control it more manually from scripts.

This thread provides some details:
https://forum.soundflow.org/-1173/how-to-change-decks-on-stream-deck-based-on-modifier-keys-held

The code in that thread will change the entire Deck based on what modifier keys you're holding down - and also which app is active. So it would be a custom replacement for Application Triggers more or less.

I know that @JesperA is also doing stuff with double clicks.

In other words - yes it's possible to do what you have envisioned, but it's not yet as "native" to do as just designing it in our Deck designer.

Hey Diego.

About modifier keys. Correct me if I'm wrong @chrscheuer but we can't read if a streamdeck key is pressed down or when it's release currently, so you can't use it as a modifier key. Would be a neat thing to have at some point for sure though.
But you can use your regular keyboard in combination with the streamdeck. This is very powerfull. The commands need to be script based and not Macros. To implement that have this code

var modifiers = event.keyboardState.asString;

if (modifiers.match('cmd')){
      // the functions you want to happen if cmd is pressed down at all, also if cmd and shift is pressed.
}
else if (modifier == 'shift'){
      // the functions you want to happen if only shift is pressed down
}
else {
      // what the script will execute in all other cases. 
}

You will have to specify more precisely if you wanna use multiple modifier keys. You can read what the modifier string is like by putting this in a script and run it while holding down some modifiers:

var modifiers = event.keyboardState.asString;
log(modifiers)

About double clicks
So it's possible fairly easy to implement double clicks for a streamdeck if your command is a scripts. Use this code:

var now = Date.now() - 0;
if (now - globalState.lastTime < 1000) {
    log('doubleClick')
    throw 0;
}
globalState.lastTime = now;

This will do the action if you double click within 1 second (1000ms).
If there's an action for single click, and you have that before this small snippet of code it will do the first action twice. If you have it after this code, it will only do it once.
A way to get around that would be:

var now = Date.now() - 0;
var doubleClickSpeed = 1000
globalState.ifDoubleClick = false

if (now - globalState.lastTime < doubleClickSpeed) {
    globalState.ifDoubleClick = true
    log('doubleClick')
    throw 0;
} else {
    globalState.lastTime = now;
    sf.wait({ intervalMs: doubleClickSpeed, executionMode: 'Background' })
    if (!globalState.ifDoubleClick)
        log('singleClick')
}

Cool thing is this could even be applied to regular key strokes or other inputs.
One thing to note is about the globalState especially the lastTime I have above. If the same globalState is used in multiple scripts, for instance two different commands on two different streamdeck keys, and you press the two different SD keys within 1000ms, the second one will run the double click. So you could consider making specific globalState names for different script for the lastTime globalState.
