+# Search engines which can be used via the address bar.  Maps a search
+# engine name (such as `DEFAULT`, or `ddg`) to a URL with a `{}`
+# placeholder. The placeholder will be replaced by the search term, use
+# `{{` and `}}` for literal `{`/`}` braces.  The following further
+# placeholds are defined to configure how special characters in the
+# search terms are replaced by safe characters (called 'quoting'):  *
+# `{}` and `{semiquoted}` quote everything except slashes; this is the
+# most   sensible choice for almost all search engines (for the search
+# term   `slash/and&amp` this placeholder expands to `slash/and%26amp`).
+# * `{quoted}` quotes all characters (for `slash/and&amp` this
+# placeholder   expands to `slash%2Fand%26amp`). * `{unquoted}` quotes
+# nothing (for `slash/and&amp` this placeholder   expands to
+# `slash/and&amp`). * `{0}` means the same as `{}`, but can be used
+# multiple times.  The search engine named `DEFAULT` is used when
+# `url.auto_search` is turned on and something else than a URL was
+# entered to be opened. Other search engines can be used by prepending
+# the search engine name to the search term, e.g. `:open google
