+ To make the command @kbd{C-x 5 o} work properly, you must tell Emacs
+how the system (or the window manager) generally handles
+focus-switching between windows. There are two possibilities: either
+simply moving the mouse onto a window selects it (gives it focus), or
+you have to click on it in a suitable way to do so. Unfortunately
+there is no way Emacs can find out automatically which way the system
+handles this, so you have to explicitly say, by setting the variable
+@code{focus-follows-mouse}. If just moving the mouse onto a window
+selects it, that variable should be @code{t}; if a click is necessary,
+the variable should be @code{nil}.

+@node Drag and drop
+@section Drag and drop in Emacs.
+
+@cindex drag and drop
+ Emacs supports drag and drop so that dropping of files and text is handled.
+Currently supported drag and drop protocols are XDND, Motif and the old
+KDE 1.x protocol. There is no drag support yet.
+When text is dropped on Emacs, Emacs inserts the text where it is dropped.
+When a file is dragged from a file manager to Emacs, Emacs opens that file.
+As a special case, if a file is dropped on a dired buffer the file is
+copied or moved (depends on exactly how it is dragged and the application
+it was dragged from) to the directory the dired buffer is displaying.
+
+@vindex x-dnd-test-function
+@vindex x-dnd-known-types
+ When a user drags something from another application over Emacs, that other
+application expects Emacs to tell it if Emacs can handle the data that is
+dragged. The variable @code{x-dnd-test-function} is used by Emacs to determine
+what to reply. The default value is @code{x-dnd-default-test-function}
+which accepts drops if the type of the data to be dropped is present in
+@code{x-dnd-known-types}. You can customize @code{x-dnd-test-function} and/or
+@code{x-dnd-known-types} if you want Emacs to accept or reject drops based
+on some other criteria.
+
+@vindex x-dnd-open-file-other-window
+ A file is normally opened in the window it is dropped on, but if you
+prefer the file to be opened in a new window you can customize the variable
+@code{x-dnd-open-file-other-window}.
+
+@vindex x-dnd-types-alist
+ If you want to change the way Emacs handles drop of different types
+or add a new type, you shall customize @code{x-dnd-types-alist}. This
+requires detailed knowledge of what types other applications use
+for drag and drop.
+
+@vindex x-dnd-protocol-alist
+ When an URL is dropped on Emacs it may be a file, but it may also be
+another URL type (ftp, http, etc.). Emacs first checks
+@code{x-dnd-protocol-alist} to determine what to do with the URL. If there
+is no match there and if @code{browse-url-browser-function} is an alist,
+Emacs looks for a match there. If no match is found the text for the URL
+is inserted. If you want to alter Emacs behaviour you can customize these
+variables.

The @dfn{tool bar} is a line (or multiple lines) of icons at the top
of the Emacs window. You can click on these icons with the mouse
use of dialog boxes. This also controls whether to use file selection
windows (but those are not supported on all platforms).
+@vindex use-file-dialog
+ A file selection window is a special kind of dialog box for asking for
+file names.
+
+ You can customize the option @code{use-file-dialog} to suppress the
+use of file selection windows even if you still want other kinds
+of dialogs. This option has no effect if you have suppressed all dialog
+boxes with the option @code{use-dialog-box}.
+
+@vindex x-use-old-gtk-file-dialog
+ For Gtk+ version 2.4, you can make Emacs use the old file dialog
+by setting the variable @code{x-use-old-gtk-file-dialog} to a non-@code{nil}
+value. If Emacs is built with a Gtk+ version that has only one file dialog,
+the setting of this variable has no effect.
