Emacs Advent Calendar 09: Windows
At first there is some Emacs specific terminology to clear up: What today in modern GUIs is called a "window" is a "frame" in Emacs. Those frames won't be the topic for today, but the things that Emacs calls "windows": Frames can be split into several windows, displaying exactly one buffer each.
Note that a buffer can appear in multiple windows. Changes made to the buffer in one window are also shown other associated windows.
A window can be split into two windows which will be positioned one
above the other (
C-x 2) or side by side (
To switch from one window to the next, use
C-x o. The next
window can be scrolled with
C-M-v without giving focus to
it. Note that the last key combination won't work on most text
terminals, but will under X.
If you like the focus to follow mouse from one window to the next
without having to click in the target buffer, set the variable
mouse-autoselect-window to a non-nil value (
customize-variable <RET> mouse-autoselect-window <RET>).
You can make a window the only window in a frame with
1. To remove the current window from a frame, press
0. Windows can be resized most conveniently by clicking and
dragging the mouse on the modeline and the divider, respectively. For
key combinations to the same effect refer to the reference manual.
There are convenient versions of some commands already seen that perform an action in another window. These have a '4' stuck in their key sequence:
C-x 4 fvisits a file in another window.
C-x 4 bswitches to a buffer in some window.
C-x 4 rvisits a file read-only in another window.
C-x 4 dopens a directory in another window (mentioned here for future reference,
diredwill be a topic later on).
More details on this topic can be found in section 20 (Windows) of the Emacs Reference Manual.Tags: emacs
