Yes, I would call this trick “CooL” .. It really is.
It works like this, suppose you have google.com open on a tab, and you want to open yahoo.com on another tab, what you usually do is, open a new tab by clicking the ‘+’ icon, Â and type in the address, and hit enter. Â Right ?
Instead of this, what if you could type in yahoo.com on the current tab ( where you have google.com open ) hit ALT and Enter key together, and open it on a different tab ? In other words, you are on a tab, you enter a different address or a search keyword on the addressbar, and you get it open in a new tab.
Like it ? I did !  Try it, you will definitely like it !!

this is good. i face this problem lotts of time and than have to do a copy paste. but this is surely nice shortcut
Yes it is !!
any way to change this to the default action ?
(like tabmixplus for firefox)
hi, sorry, I didnt understand your question !
Wanting to know how to do this as well. What amir means is, how can we make it the default behavior to always open addresses in a new tab without having to do a key combo or some other nonsense. TabMixPlus is a popular addon for firefox that allows you to set what things are automatically opened in a new tab as well as many other things.
Another option is CTRL-T (to open a new tab), ALT+D (or CTRL-L) to go to the address line, type “yahoo” (without quotes) in the address bar and hit CTRL+Enter to automatically turn “yahoo” into “www.yahoo.com”.
@peter hoeg: yeah that’s the trick. it also can combined with this ALT+ENTER tip too. so you just press ALT+D to go to address bar, typing the dotcom domain name such as google, yahoo or facebook then press ALT+CTRL+ENTER. Yeeeha, it will be opened on the new tab including the dot com too. Great!
