Simple question: How do I toggle between HIDSS Navigation and HIDSS Target Acquisition Modes? whenever I get into HIDSS Target Acquisition Mode, I can't figure a way to revert to HIDSS Navigation mode. Cntr-Del seems to turn off HIDSS Target Acquisition Mode, but does not return HIDSS display to Navigation.

Also, until I get better at flying and landing, is there no way to turn off collision in Skirmish/Campaign modes like there is in Free Flight?

Thanks for your help.
