Here is a convenient & versatile yet stependously easy trick you can do in Google Chrome, leveraging the built-in custom search engine functionality:
Now, Whenever you want to visit a subreddit, simply jump to the Address Bar (Alt + D or F5 on Windows/Linux, Command + L on Mac), type in “r”, hit Tab, followed by the subreddit and then hit Enter; and you should be taken there.
This is obviously not limited to the use for subreddits; you can create multiple other quick-switching “profiles” triggered by different keywords to bring you to other website URLs you visit/navigate to-and-fro frequently.
For example, if your organization uses Jira, you can set-up the following:
This will allow you to quickly navigate to any project or issue via typing “j”, hitting Tab, followed by the project/issue number in the Address Bar.
You are also not limited to create substitutions to the path segment of URLs; you can configure it to fill in any part of URLs; for example,
https://%s.google.com will let you switch to the various Google services, etc.
