Frame
Revision as of 16:10, 26 March 2012 by 115.242.207.91 (talk)
In Emacs terminology, a "frame" is what most window managers (Windows, OSX, GNOME, KDE, etc.) would call a "window".
It will typically have a title bar and some buttons to iconify (minimize), maximize / restore, and close the frame. To see an example, open up a second frame from your running Emacs instance with C-x 5 2 (make-frame-command). You can close frames with C-x 5 0 (delete-frame), though this will not close the last frame that is open.
