Finding All Frames

Function: frame-list

The function frame-list returns a list of all the frames that have not been deleted. It is analogous to buffer-list for buffers. The list that you get is newly created, so modifying the list doesn't have any effect on the internals of Emacs.

Function: visible-frame-list

This function returns a list of just the currently visible frames. See section Visibility of Frames. (Terminal frames always count as "visible", even though only the selected one is actually displayed.)

Function: next-frame &optional frame minibuf

The function next-frame lets you cycle conveniently through all the frames from an arbitrary starting point. It returns the "next" frame after frame in the cycle. If frame is omitted or nil, it defaults to the selected frame.

The second argument, minibuf, says which frames to consider:

nil

Exclude minibuffer-only frames.

visible

Consider all visible frames.

0

Consider all visible or iconified frames.

a window

Consider only the frames using that particular window as their minibuffer.

anything else

Consider all frames.

Function: previous-frame &optional frame minibuf

Like next-frame, but cycles through all frames in the opposite direction.

See also next-window and previous-window, in section Cyclic Ordering of Windows.
