You do have some options in Revit and you can set them up  via a dialog box.

Open the dialog box by clicking on the “R” (called the Application Menu)  and going to the bottom right side of the drop down and selecting Options.  Don’t hit Exit.   🙂

This opens the dialog box

It opens on the General Tab.

Once inside the dialog box you can set the following:

General: In this tab you can set notifications, user name, and journal file settings and Display settings.

Graphics: Here you  enable hardware acceleration, configure colors for selection, highlight, background, and alerts, and enable anti-aliasing for 3D views.

File Locations: Specify paths for default file locations and directories.

Rendering : Specify paths for files used for render appearances and decals, and specify the location of the ArchVision Content Manager.

Spelling : Specify options for the spell checker like what to ignore and where dictionaries are located.

SteeringWheels : Specify options for the SteeringWheels view navigation tools like Look, Walk, Zoom and Orbit tools.

ViewCube : Specify options for the ViewCube navigation tool like view,snap clicking options and the compass.

Macros: Settings foe Application and Document Macros.

You can set these at any time even when you have no file open.
