A few of the other search engines let you do "!g" in your query which automatically takes you to a google search instead.

For example: DuckDuckGo.

You can set google as a search engine then when you type "google.com <space>/<tab>" and it will switch the search engine for this one query. You can edit the exact keyword and set whatever search engine you want in settings -> "search engines" in google.

I got an extension that just adds a "search on google" option at the top of any duckduckgo search results page. For most things DDG suffices fine but when it isn't I'll just have to do one extra click.

This feels like a better flow to me than having to remember when I explicitly need to use google in the address bar or having to go to google.com and search it there.

You can just click the Google icon in your search box and it will then search with Google.
