Attached Firefox/Internet Explorer search plugin. In Firefox, when you are on Stack Overflow, just click on the search dropdown (to the left of the search text field) and hit Add "Stack Overflow".
EDIT: SO-family sites now also support OpenSearch, as described in this question.

Does this only work on Windows? It doesn't work on the ancient version of Firefox on my CentOS box. Commented Oct 7, 2008 at 19:29

2It has to support the "manage search plugins" option, and have discovery working. I'm using Firefox 3.0.2 on Fedora 9, so it definitely works under linux. It may just be that your version of firefox doesn't autodiscover.– akdomCommented Oct 7, 2008 at 19:31

Take a look a the originating post stackoverflow.com/questions/20830/… . You will need to adjust it since that was for beta.stackoverflow.com (if it doesn't still work). But you can manually add it with that.– akdomCommented Oct 7, 2008 at 19:33

4Cool, but nowhere near hidden. Lots of sites have this (more should!). And you can add sites yourself easily by generating the needed XML by searching a site for TEST and entering the resulting URL into microsoft.com/windows/ie/searchguide/en-uk/default.mspx– peSHIrCommented Jan 22, 2009 at 13:31

1It get's better if you assign a keyword to StackOveflow as search engine for Firefox (e.g. "so"). You can then type something like "so python+hidden" directly as URL into Firefox. Commented May 23, 2009 at 12:05

<kbd>Ctrl</kbd> + <kbd>Alt</kbd> + <kbd>Del</kbd>

1@Tink huh didn't notice it was deleted. Don't think that when a hidden feature is gone the answer about it should be deleted, if anything it has historical value, so we know what used to be here. A notice can be added on top of such answers instead, I do that sometimes. Commented Jan 22 at 9:28

Wildcards in tag filters
Adding *C#* to your ignored tags will ignore any tag that contains the letters C#, including C#-4.0 and visual-C#-express-2010. Likewise for favorite tags.
This is useful because there are often questions tagged C#-3.0 but not C#, so just ignoring C# wouldn't catch this. Its a really nice solution to ignoring all questions on a given topic.
You can even use it to ignore all questions not in your favorite tags by just ignoring * :D
-
Single most useful feature I've seen yet. I don't know why I didn't think to try that!– ChipsterCommented Dec 29, 2019 at 3:21

Note that wildcarding returns a maximum of 20 tags, so if you set a really generic term as a filter with wildcards you may still get tags appearing that you don't want to see.– RobotnikCommented Jan 21 at 23:23
I recently learned that the Your Question/Your Answer editor has an auto-indent feature (in source code blocks): Try Shift+Enter.
-
39Actually Shift+Enter is a continue formatting command: I.e. it doesn't continue extra indenting within code, but it does add the first 4 needed spaces if you're already in code. It also adds the next numeric value for a numbered list, a copy of the first mark for an unnumbered list, and for both of the latter it "fixes" the other numbers/marks to be sequential/the same. It also continues > blockquotes. Commented Jul 10, 2010 at 3:16

You can search for multiple tags by typing them in the URL separated by %20. This does an AND search, i.e. only questions with all the tags you specified will be shown.
For example:
searches for both the 'windows' and the 'com' tags
Alternatively you can type the following in the search box in the top right for the same results:
[windows] [com]

It'd be nice if they enabled the word 'AND' but i'm happy to learn about this, thanks. Commented Oct 7, 2008 at 19:11

It's possible to view the markup used to create any question or answer. (This may be useful if you wish to combine answers or quote part of the question with formatting.)
If the question or answer has been edited so that it has an edited X timeunits ago link, you can use that to view the revision history, then use the view source link.
If it hasn't been edited then you can still view the revision history, but you'll have to manually enter the url in your browser's address bar. For questions, take the number in the middle of the page's url; for answers use the link link for the answer to get it's unique number in the anchor of the url (after the # character) and then go to:

When you search for a popular keyword the search gets auto-converted to a tag search.

Every site on Stack Exchange network has a "network login help" page, which run a few tests to check for the availability of certain necessary features in the user's browser.

- m -> medium thumb (max 320?)

Easier than going to the full sites list and looking for the site you want. :)

I don't really see how Mehdi's edit made the post worse. It was minor, but I think most of it was an improvement.

@starball nope. You can't see multiple users reviews in one place, you see single user reviews each time, so "user's" is the only correct word.
