+# 2. Adding key bindings
+# --------------------
+
+# As a demonstration, we will add just a ControlQ key binding to exit the
+# application. Key bindings are registered in a
+# `prompt_toolkit.key_bindings.registry.Registry` instance. We use the
+# `load_default_key_bindings` utility function to create a registry that
+# already contains the default key bindings.
+
+kb = KeyBindings()
+
+# Now add the Ctrl-Q binding. We have to pass `eager=True` here. The reason is
+# that there is another key *sequence* that starts with Ctrl-Q as well. Yes, a
+# key binding is linked to a sequence of keys, not necessarily one key. So,
+# what happens if there is a key binding for the letter 'a' and a key binding
+# for 'ab'. When 'a' has been pressed, nothing will happen yet. Because the
+# next key could be a 'b', but it could as well be anything else. If it's a 'c'
+# for instance, we'll handle the key binding for 'a' and then look for a key
+# binding for 'c'. So, when there's a common prefix in a key binding sequence,
+# prompt-toolkit will wait calling a handler, until we have enough information.
+
+# Now, There is an Emacs key binding for the [Ctrl-Q Any] sequence by default.
+# Pressing Ctrl-Q followed by any other key will do a quoted insert. So to be
+# sure that we won't wait for that key binding to match, but instead execute
+# Ctrl-Q immediately, we can pass eager=True. (Don't make a habit of adding
+# `eager=True` to all key bindings, but do it when it conflicts with another
+# existing key binding, and you definitely want to override that behaviour.
+
+
+@kb.add("c-c", eager=True)
+@kb.add("c-q", eager=True)
+def _(event):
+ """
+ Pressing Ctrl-Q or Ctrl-C will exit the user interface.
+
+ Setting a return value means: quit the event loop that drives the user
+ interface and return this value from the `Application.run()` call.
+
+ Note that Ctrl-Q does not work on all terminals. Sometimes it requires
+ executing `stty -ixon`.
+ """
