If your not confused by now...
Allow me to give you a near complete (near) list of "hot keys"
W = Shows/hides water
H = Shows/hides Blight
S = Shows/Hides Shadows
L = Shows/hides Lighting (Attached to options, will show/hide land shadows)
E = Shows/Hides Weather (both Global and regional)
K = Shows/Hides the sky
F = Shows/Hides the fog (Atmospheric fog, not regional fog effects)
G = Shows Grid/ hit multiple times for different grid sizes
B = Hows/Hides camera bounds (the blue line around your map)
P = Shows ground pathing - blue unbuildable, Pink unwalkable, white unwalkable, unflyable, etc.
N = Shows naval pathing - orangy pinky means no ships can sail
To open up tool pallets:
T = Terrain
D = Doodads
U = Units
R = Regions (Rects if you use World Editor Unlimited)
M = Cameras
To Show/Hide those "layers)
While holding Control key (CTRL)
CTRL + T = Hides the terrain with either colored frame or completely (hit twice)
CTRL + D = Hides/Shows the Doodads (all of them)
CTRL + U = Hides/Shows Units
CTRL + R = Hides/Shows regions
CTRL + M =hides Shows Cameras
Camera:
V = Came View (Turns on all weather, light, fog, hides pink doodad boxes, pathing, etc.
C = Game Camera, will lock the distance and the angle of attack to the game camera.
X = Letter box mode, cuts the image down to what is seen in cinematic mode.
To move your camera about:
Arrow Keys by themselves move the camera north, south east and west. If you have turned your camera to face west, then the up arrow key will move the camera west.
While holding the control key (CTRL)
CTRL + Arrow up = Zooms in
CTRL + Arrow Down = zooms out
CTRL + Arrow Left = rotates the camera Counter clockwise
CTRL + Arrow Right = rotates the camera Clockwise
CTRL + Shift and the arrow up key will shorten the Far Z meaning the sky box will come closer devouring the landscape
CTRL + Shift and the arrow down key will push the sky box away, allowing you to see more land scape.
As for moving the camera for the angle of attack the only way I know is through holding down the CTRL key and using the Right Mouse Button to scroll about.
To move units/doodads blah select one or more at a time and use the number pad (num lock on)
To select all the units/doodads of a kind select one of them and hit CTRL + SHIFT and the button that has ~ and ` on it (the one left of the 1 button).
Delete of course deletes the selected units/doodads, regions, blah.
If you do not like any of these control settings, you can go to the menu bar at top, select File configure Controls - every single thing you can do can be found under that.
