Internet Explorer has long had a very useful "hidden feature": a shortcut for quick searches from the address bar, allowing you to use any number of websites as search providers (as described in an answer to What do all of Internet Explorer's search settings mean?; the settings are stored in the registry at
For example, if I associate the shortcut
"su" with the address
"http://superuser.com/search?q=%s", I could type
"su Internet Explorer" in the address bar and instantly get this resulting page.
However, the only way to set up and maintain it (that I know of) is by editing the registry (as described in Windows 7 : Using Any Search Engine from the Address Bar; archived here), or by installing a utility like Tweak UI (a Windows XP powertoy that is apparently no longer officially supported). At work I don't have administrator privileges to my workstation, so those options won't work for me. Is there another way to expose this feature?
