When the editor is called up an editor window is created and displayed (for those already familiar with Emacs running on a tty terminal, note that in this context a window is an object used by the window manager to display data, and not a term used to describe a portion of the editor display). The largest area of the editor window is taken up by an editor pane. Each window contains a single pane and therefore the term window is used throughout this manual as being synonymous with pane , unless more clarification is required.
Initially only one editor window is displayed. The corresponding editor pane is either blank (ready for text to be entered) or contains text from a file to be edited. The editor window displays text using the font associated with the editor pane.
