Launch Apps | Layer

Launch apps by layer + keys. When press and hold key l to activate the 'launch-app' layer:

• c: Calendar
• f: Finder

Use any key for the layer, also consider using:

• simlayer('l', 'launch-app')
• hyperLayer('l', 'launch-app')
• duoLayer('l', ';', 'launch-app')

Copy and edit the code below in the online editor:

export const rules = () => [
  layer('l', 'launch-app').manipulators({
    c: toApp('Calendar'),
    f: toApp('Finder'),
  }),
]
