Crosshair cursor
When this is enabled, the pointer will turn into a crosshair when it is over a brush.
Default to 15 degree rotations
When rotating a brush, the rotations will automatically be in 15 degree increments.
Display scrollbars
If this is disabled, scrollbars will not appear in the 2D views. You will be able to scroll the views by using the arrow keys.
Draw Vertices
If this is enabled, brush vertices will be shown in the 3D views.
White on black color scheme
Brushes will appear as white lines drawn on a black background. When this is not enabled, the reverse is in effect.
Keep grouping when clone dragging
When clone dragging (selecting an object, holding down shift, and dragging the object), this will enable the newly cloned object to retain any grouping properties of the original object.
Center on camera after movement in 3D
While in camera mode, if you use the mouse to move around the 3D view, the 2D views will automatically center on the new camera position if this option is enabled.
Use Visgroup colors for object lines
When this is enabled, the object lines for any non-entity brush will be whatever color is specified in their visgroup when viewed in the 2D views. Objects not associated with a visgroup will still appear white.
Arrow keys nudge selected object/vertex
When this is enabled, you can move a selected object or vertex by using the arrow keys. Note that the mouse cursor's position in the 2D views will dictate which direction the object will move.
Reorient primitives on creation in the active 2D view
When this is enabled, primitives will be oriented with their "top" shown in whichever 2D view it was created in. This is most easily shown when creating a cylinder. With this option disabled, the cylinder will be oriented so that the round part shows up in the xy 2D view, regardless of which view you created it in. This is mostly just a time saving feature.
Automatic infinite selection in 2D windows (no ENTER)
When this is enabled, dragging a selection box over an object or objects will immediately cause them to be selected (normally you would need to press ENTER). This option can be turned on and off from the button bar as well (see Toggle auto-selection).
Selection box selects by handles only
When using a selection box to select a number of objects, it defaults to selecting any object the box touches. With this option enabled, it will only select those objects whose "handles" (the small "x" at the center of each object) are within the selection box.
Grid: Size
This will be the initial grid size when you start a new map. The options are 8, 16, 32, 64, 128, and 256 units. You can change the grid size while editing by pressing "[" and "]".
Grid: Intensity
This is a slide bar from 0 to 100. It sets the intensity (brightness) of the grid lines.
Grid: Highlight every 64 units
This will highlight the grid every 64 units.
Grid: Highlight every [nnn] grid lines
This will highlight a grid line once every nnn lines.
Grid: Hide grid smaller than 4 pixels
If the grid size is smaller than 4 pixels, it will generally appear as a gray background instead of a grid, unless zoomed in extremely close. When enabled, this option turns off the grid when it gets that small.
