Apple’s new browser Safari 5 has a very capable feature called ‘Reader’. This feature enables a distraction free webpage text reading; just like reading a PDF document.
It strips out all the advertisements and extraneous layout from a webpage so that you can very easily read a webpage text.
To use this, after installing, when you enter a web page that is identified as an article, iReader icon will appears on the address bar.
Just click the icon or use the keyboard shortcut ( Ctrl+Shift+P) for Windows and Linux, and (?-Shift-P) for MAC) to open iReader window.
To close iReader and return to the webpage, click anywhere in the background or click iReader icon again.
