I know most of your are GC1 players, so most of this is already known...but I'll post it just in case. Actually, alot of the 3d stuff is new, so hopefully my terminology isn't...well, wrong. 
**Main Map Controls**
-When any Map Object is Selected (Planets, Stars, Ships, Anomalies)
- Left Mouse Button: Select another object. Click and Drag to move pan.
- Hold Middle Mouse Button: Rotate around the current View.
- Scroll Middle Mouse Button: Zoom In and Out of the Map. Hold Shift for Slower, more Precise Zooming.
-When a Players' Ship Is Selected
- Right Mouse Button: Set Ship Destination. Attack by setting another Race's ship as your destination. Set a Colony Ship to Colonize A Planet By Right Clicking on the Planet. Set a Transport to Invade by Right Clicking on an enemy planet.
**Mini Map Controls**
- Left Click: Move Current Viewing Area of Main Map.
- Right Click: Set Destination of Currently Selected Ship.
- Scroll Middle Mouse Btn: Zoom in and Out.
** HotKeys **
- F1-F3: Snap to three different Angular views of the main Map
- F4: Snap to a present Overhead view of the main map (Most like GC1)
-When a Players' Ship Is Selected
- D - Decommission Ship
- T - Auto-Attack
- S - Sector Sweep
- TAB - Go To Next Available Ship with Moves.
This should be a good start for everyone. If there are any control questions, just post here and I'll get you an answer ASAP (or a fellow player may be able to provide the answer).
Have fun!
