Two Questions about Enhanced Menu

[SilencerVader]

Just two quick questions about the enhanced menu:

1. What's the hotkey for setting up shortcuts for functions? Like binding a key to spawn a certain vehicle. I accidently did it once but don't know how.

2. I saw there's a feature called unlock GTA+ or sth, I wonder if it unlocks the 4X money provided to GTA+ members? Is it safe to use? (Relatively speaking of course, compared with other Recovery options)
