2. What it "The Singularity Key Press Add On Profile" does

The Singularity Key-Press Add-on is an add-on VAP (Voice Attack Profile) that works alongside your HCS Voicepack ( it also works with multi-crew ! ) when using VoiceAttack with the HCS Elite: Singularity profile.

It's main purpose is to instantiate direct HCS voice responses from your keyboard & numeric keypad's key-presses. All the key-press voice responses are given by the crew-member assigned to the "OPERATIONS" role.
