How to Quickly Select Multiple Mails in GMail

Your Web GMail displays 50 emails in rows, but you want to select #1 - #30 and perform a specific action to it. There’s no need to select the checkbox one by one for 30 times, or click the “Select all’ and uncheck each of the unwanted 20. Ashish of Technospot found a shortcut to mass select the emails All you need to do is select the first, hold Shift key and select the last and you’ll notice everything in the middle will be selected as well.
