Aurora has support for Apple Remote control of several parts of the program.
In Playback mode, use the Play/Pause button to start or cancel Snooze, the Menu button to stop the alarm, the Volume buttons to control playback volume and the Next button to skip the currently playing track.
In Fall Asleep mode, use the Play/Pause button on your Apple Remote to start or cancel fall asleep.
In Alarm list mode, use the Play/Pause button on your Apple Remote to try out the currently selected alarm.
You can fully disable Apple Remote support in Aurora (for better interaction with applications such as Sofa Control) by quitting Aurora and pasting the following into a Terminal window: defaults write com.oneperiodic.Aurora EnableAppleRemote -bool false (or, true to re-enable it).
