Scroll to Top - one press to the top

Are there times that after you read a really long post, you just have to go through the trouble of scrolling all the way to the top of the page? Have you ever imagined a simple click on a button that takes you to the top for every page? Here comes the easy-to-use Chrome extension that just does this fantastically. One press and it takes you to the top. It automatically finds out whether the current page can be scrolled up by the extension. If it is grey, it means either the page is already near its top or the page does not allow extension scrolling. If it is green, one click, it does all the magic for you. Simple and easy! You can also use Command+Shift+Z on Mac or Ctrl+Shift+Z on others as shortcuts.
