Maybe it's just me, but I keep trying to use the right mouse button to zoom out when viewing the galactic map.

Something says to me that if the LMB zooms in, RMB should zoom out.

Sure, a fraction of a second later, my brain kicks in tells me to press <Esc> instead.

This strikes me as one of those "quick win" developer tasks that should be fairly low on the to-do list, but because it's so easy to implement it can be thrown in quickly. yeah, yeah, I know... wishful thinking
