+# incremental-complete-word() {

+# Autoload this function, run `zle -N <func-name>' and bind <func-name>
+# to a key.
+
+# This allows incremental completion of a word.  After starting this
+# command, a list of completion choices is shown after every character you
+# type, which you can delete with ^h or DEL.  RET will accept the
+# completion so far.  You can hit TAB to do normal completion and ^g to
+# abort back to the state when you started.
+#
+# Completion keys:
+#   incremental_prompt   Prompt to show in status line during icompletion;
+#                        the sequence `%u' is replaced by the unambiguous
+#                        part of all matches if there is any and it is
+#                        different from the word on the line
+# incremental_stop       Pattern matching keys which will cause icompletion
+#                         to stop and the key to be re-executed
+# incremental_break      Pattern matching keys which will cause icompletion
+#                         to stop and the key to be discarded
+# incremental_completer  Set of completers, like the `completer' key
+#   incremental_list     If set to a non-empty string, the matches will be
+#                        listed on every key-press
