Thanks Chocohead. Do I need to log that as a change request somewhere?
Documentation for the key combination Boost Key + Mode Switch Key to enable/disable Jetpack mode was added to http://wiki.industrial-craft.n…tle=QuantumSuit_Bodyarmor by Escain, Revision as of 19:53, 21 January 2015. That's different from the Gravitation activation key documented at [IC2 Exp][1.7.10] Gravitation Suite v2.0.3! – so it looks like there was intent to implement it at one time.
