+# Show Matching Entries For Help
+
+Looking up things with Vim's `:help` command can be error prone if you don't
+know exactly how to format what you are looking up. Bypass some of the
+guesswork by hitting `Ctrl-d` after writing part of the `:help` command.
+This will populate a wildmenu of possible matches.
+
+For instance, if you know there is a command containing `?`, but you aren't
+sure how to look it up, try the following:
+
+```
+:help ?<Ctrl-d>
+```
+
+You can tab through to the one you want and hit enter to read up on it. Who
+knew there were so many Vim bindings involving a `?`.
+
+See `:h help-context` for more details.
