Creating a frame

Create a frame by dragging a frame border or by choosing commands in the Modify menu.

There are two ways to create new frames:

Choose Modify > Frameset > Split Frame Up, Down, Left, or Right.
Choose View > Frame Borders and Alt-drag (Windows) or Option-drag (Macintosh) a frame border into the document window to split the frame vertically or horizontally. Drag from one of the corners to divide the current frame into four new frames.

See Frames overview for an animated introduction to creating frames.
