Will you have some native "longpress handleKey" support? about lightning HOT 2 CLOSED

There is now an feature branch available that supports keyup and longpress:
https://github.com/WebPlatformForEmbedded/Lightning/tree/feature/Longpress

Depending on the exact keymapping you can set the following handlers on your component:
i.e Left:

// this will fire on normal keypress left
_handleLeft(){ 
}

// this will fire when you release the left key
_handleLeftRelease(){
}

// this will fire when you keep pressing left for a given time:
_handleLeftLong(){
}

// you can configure the timing (in ms) via the template
static _template(){
 return {
  w: 100, h:100,
  longpress:{left:600, up:800, right:1200, down:400}
 }
}

We're now testing the functionality and will notify you when it's available in master

Hey, this is indeed not the docs. For long press to work work we need to register and listen to keyup events, and Lightning currently is not, we only listen keydown events. To create some best practices we first need to register keyup events so we can create some configurable long press handlers.
