There are a lot of games that use jump/crouch keybinds to raise/lower the camera while in a free-spec-editing-flying-whatever state. I figured it would be a welcomed addition since most people would be used to it. I am, UT2K4 ftw. :D
As far as moving slower in edit mode, no way. The flyspeed variable leaves how fast you want to move in edit mode entirely up to you. (to a certain extent - flyspeed 5.0 is crazy :p)
It can always be tweaked if necessary and it isn't the end of the world.
P.S. We'll update the docs about all the new mapping features ASAP. If you want to play around with multiple selections, make a selection as you would normally, then hold the left control key (LCTRL) and make more. You can manipulate geometry/textures in bulk using this method. :D
