Here's what happened
Having just today come into possession of a Corsair K95 RGB Cherry MX red keyboard, I tried to replicate the setup I had on my Logitech G11 by remapping the macro keys to run various programs, except I could not find how to do so.
I even downgraded to CUE v1 at some point because I thought it was simply not possible in v2. Then went I back to v2 on principle and somehow found the solution.
Exact version of CUE is `2.4.66`.

Sounds simple when you read it but not exactly intuitive when going through the UI. See the following screenshot for illustration.
Guess we're done here.
