+@subsection Legacy Global Key Binding Commands
+
+@findex global-set-key
+@cindex Global set key
+Historically, keys are bound globally using a lower-level function,
+@code{global-set-key}, which is now considered legacy.  While you are
+encouraged to use @code{keymap-global-set}, you likely would encounter
+@code{global-set-key} in various places.  The first example in this

+
+@smallexample
+@group
+(global-set-key "\C-cw" 'compare-windows)
+@end group
+@end smallexample
+
+It is very similar to @code{keymap-global-set}, with the keybinding
+following a slightly different format.  Control-C is represented by
+@code{\C-c}, instead of @code{C-c}.  There is no space between key
+strokes, like @code{\C-c} and @code{w} in this example.  Despite the
+difference, in documentation, this is still written as @w{@kbd{C-c w}}
+for readability.
+
+@findex global-unset-key
+Historically, keys are unbound globally using a lower-function,
+@code{global-unset-key}, which is now considered legacy.  Its key
+binding format follows that of @code{global-set-key}.  The key unbinding
+example in this section can be rewritten as:

 Emacs uses @dfn{keymaps} to record which keys call which commands.

+When you use @code{keymap-global-set} to set the key binding for a
+single command in all parts of Emacs, you are specifying the key binding

 Specific modes, such as C mode or Text mode, have their own keymaps;
 the mode-specific keymaps override the global map that is shared by
 all buffers.
