This is a neat trick for copying columns of text from a table into some other application. This is particularly useful when you don’t need the whole table of information, and just want one column or several columns (e.g. just the usernames from a list of members).
I haven’t tried it on other browsers, but it works for me in Firefox 3.6.2. (Another reason why I love Firefox – it’s just so full of functionality). I’m particularly impressed that it’s something that I wouldn’t know that exists, but they’ve already thought ahead about it, and have it fully implemented already.
So here’s the trick – on the Mac, just hold down the Cmd key and select the column that you want by clicking and dragging with your mouse. On Windows, it’s the Ctrl key.
