We use pre tags to display the embed codes and short URLs. We use pre tags because it formats the text inside the tags as we insert it, which is ideal for displaying code in particular. The thing is, people like to copy this code and they have to go to the awful bother of selecting all the text manually if they wish to copy the code or URL.
jQuery hack to auto select all the text inside the pre tags. The only complication with this appears to be a cross platform solution as each browser appears to have their own way of selecting text.
here goes the code :

Internet Explorer uses createTextRange.
Opera and Firefox use createRange.
Safari uses DOMSelection.
Opera and Firefox use createRange.
Safari uses DOMSelection.
So with a pre tag like (just click anywhere in the code)…
jQuery( document ).ready(function() {
jQuery( 'pre.code' ).click( function() {
var refNode = $( this )[0];
if ( $.browser.msie ) {
var range = document.body.createTextRange();
range.moveToElementText( refNode );
range.select();
} else if ( $.browser.mozilla || $.browser.opera ) {
var selection = window.getSelection();
var range = document.createRange();
range.selectNodeContents( refNode );
selection.removeAllRanges();
selection.addRange( range );
} else if ( $.browser.safari ) {
var selection = window.getSelection();
selection.setBaseAndExtent( refNode, 0, refNode, 1 );
}
} );
} );
