A fairly straightforward macro/hotkey program for Adafruit MACROPAD.
|
|
Macro key setups are stored in the /macros folder (configurable below),
|
|
load up just the ones you're likely to use. Plug into computer's USB port,
|
|
use dial to select an application macro set, press MACROPAD keys to send
|
|
key sequences.
