Nifty features you may not have known about

This is a list of cool things that not all redditors seem to know about. Please send us feedback if you can think of ways to make these features more discoverable.

Misc

• When a submission's number is colored, it means it's reached the #1 spot on reddit. Clicking on this number will take you to a running list of all the #1 reddit links.
• Both the reddit toolbar and bookmarklets have a "serendipity!" button, which takes you to a random link in the reddit queue. You can also go to http://reddit.com/r/[reddit]/random to get a random link from a particular reddit.
• You can see the most recent comments across all of reddit by visiting reddit.com/comments . This works for subreddits too, by going to /r/(subreddit)/comments .
• A dotted outline around a headline indicates a link you just visited. This makes it easier to up-vote, down-vote or comment on the submission once you return to Reddit.

Pseudoreddits and other URL tricks

• You can view posts from multiple reddits by separating them with '+' characters in the URL, such as reddit.com/r/technology+wtf/
• To view posts from all reddits, use /r/all
• To see all posts within a given domain, go to http://reddit.com/domain/[domain] -- like http://www.reddit.com/domain/microsoft.com
• To change the number of posts per page without logging in, for instance when you're using an RSS reader, add a "limit" parameter to the query string. For example reddit.com/.rss?limit=42

The toolbar

• Toolbar links can be autogenerated by prepending http://reddit.com/ to any URL. For example, if you're visiting the Wikipedia page on the Konami code (http://en.wikipedia.org/wiki/Konami_Code) and you're wondering if it was ever submitted to reddit, just go to http://reddit.com/http://en.wikipedia.org/wiki/Konami_Code (you can leave off either or both "http://"s).
• You can also get a bookmarklet to do the above for you.
• If you do the above, and the link hasn't been submitted, you'll be taken to the submit page. So this is a great shortcut for submitting links to reddit.
• If you visit http://reddit.com/[some submission id], you'll get taken to the submission. So if you're looking at
  http://www.reddit.com/r/windowshots/comments/881hc/reddit_hq_yes_thats_a_power_cord_holding_the/
  while on the phone with your significant other, you can verbally relay the short form: "reddit dot com slash eight eight one and then "hc" as in holy cow"
