One of my favorite features of Firefox is the keystroke for completing domain names. For example:

1. You use ctrl-D (on Windows or Linux) or cmd-L (on Mac) to select the address bar
2. You type in the domain name sans extension e.g. techjive
3. Depending on the extension (.com, .net, .org) you use the appropriate keystroke and it prepends a “www.” and appends the “.whatever” e.g. makes techjive = www.techjive.net

The keystrokes are:

• ctrl-Enter (Win & Linux) or cmd-Enter (Mac) = .com
• shift-Enter = .net
• ctrl-shift-Enter (Win & Linux) or cmd-shift-Enter (Mac) = .org

The .com keystroke works for Internet Explorer and Opera. For Safari, if you type in the name and just hit enter — e.g. google — it puts the .com on it for you; no keystroke needed. Firefox is the only one that goes beyond the .com with this feature.
