Once you get used to keyword searches, here are some other handy ones. It's like having a CLI to the Internet.

gm Google Maps

t thesaurus.com

u YouTube (for music)

pron for porn (after setting up a Google custom search engine that searches your favorite tube sites -- https://developers.google.com/custom-search)

gi for Google Images

r for Reddit (the site search has gotten better -- I used to use Google "site:reddit.com %s" instead).

My only problem with these is somehow the Wayback Machine doesn't work when I put https://web.archive.org/form-submit.jsp?url=%s.
