The Elgato Stream Deck is an external keypad/keyboard with a number of programable buttons.
Keyboard Maestro (v9.0+) supports the Stream Deck via an Stream Deck Plug In and the USB Device Key trigger, as well as a number of Stream Deck specific actions.
Ensure you have Stream Deck 4.2 or later installed.
Hopefully the Keyboard Maestro Stream Deck Plug In will be available directly from the Stream Deck
More Actions… button eventually. In the mean time, you can install it manually.
Download the Keyboard Maestro Stream Deck Plug In.
Double click the resulting
com.stairways.keyboardmaestro.streamDeckPlugin to install it.
For any button you want to use with Keyboard Maestro, drag the resulting Keyboard Maestro entry (in the Automation category) to a button.
In Stream Deck, you can configure the button:
You can configure the position and font and size of the title which appears in the button, as well as the title of the button.
The button also has an ID which is how you refer to it from Keyboard Maestro actions, as well as a row and column number which is how the button appears to the USB Device Key trigger. By default these will track the position of the button on the keyboard, and you should probably leave them all blank unless you have specific needs.
Since the button works the same as any other USB Device Key trigger, you can detect press, release, tap, tap twice, and so forth, giving you many ways to interact with the button.
And since you can set the title and image on the button from Keyboard Maestro, you can have a lot of feedback on the keyboard as well.
