There's no way for you, as a developer, to force a link to open in a new tab with HTML.
You could open the link in a new window, but that has long been recognized as a bad idea. Using the TARGET attribute with an A element is actually deprecated as of HTML 4.01. The main idea is that the user (not the document) should have control over spawning new browser windows (or new tabs).
As a user, a good browser will allow you to always open new pages in a new tab, if that is your preference.
i know firefox lets me open my windows as new tabs but one of my friends has a javascript enabled in his page that opens ads in new tabs - only he wont share the javascript
oops fluther blocks javascripts but heres the code <*a href="http://ziked.com" onclick="if(!event.ctrlKey&&!window.opera){alert('Please Try Again while holding down the Ctrl Key');return false;}else{return true;}" target="_blank">ZIKED
If you navigate to the newtab.js file in your browser, you can see its contents. There is no way to hide client-side code such ad javascript from the user because, by definition, the client (browser) requires the code to execute.
It's not possible to generate events external to the document in Javascript. Consider the security implications if this was possible (e.g., firing Control+Alt+Delete).
Within a document, you can use keyCode to determine what key the user presses (the keyCode for Control is 17).
"My point above was that it's not a good practice to seize this control from the user."
I agree with sferik, don't hijack the user experience, it can be very frustrating on the client end. In the old days, everyone wanted their sites to fill the screen on load, how annoying!
Really, just target=“_blank” would be fine (see points made by zacko and sferik). target=“_blank” will open in a new tab for me, because I have set it that way, and if you’ve got a bit respectable browser then you should be able to set that. In fact, this behaviour will be default for Firefox 3 (or was it already for Firefox 2?).
