+                Whether to suppress completions from other `Matchers`_.
+                When set to ``None`` (default) the matchers will attempt to auto-detect
+                whether suppression of other matchers is desirable. For example, at the
+                beginning of a line followed by `%` we expect a magic completion to be the
+                only applicable option, and after ``my_dict['`` we usually expect a
+                completion with an existing dictionary key.
+                If you want to disable this heuristic and see completions from all matchers,
+                set ``IPCompleter.suppress_competing_matchers = False``. To disable the
+                heuristic for specific matchers provide a dictionary mapping:
+                ``IPCompleter.suppress_competing_matchers = {'IPCompleter.dict_key_matcher':
+                False}``.
+                Set ``IPCompleter.suppress_competing_matchers = True`` to limit completions
+                to the set of matchers with the highest priority; this is equivalent to
+                ``IPCompleter.merge_completions`` and         can be beneficial for
+                performance, but will sometimes omit relevant candidates from matchers
+                further down the priority list.
