I just suggest that you memorize the name of the template and type it in the template search thingy. On small wikis, the top 10 templates may be used around 10 times each, but on big wikis you may need to use it hundreds or even thousands of times for it to appear there.

If you need a place where you can find a list of all template names, you can just go to Special:AllPages and search the Template namespace. And no, it doesn't really matter if you add it via the sidebar or type the code in.
