+low level interactions like mouse movements, mouse button actions , key presses and

 The implementation contains a drag_and_drop function, but due to Selenium limitations, it is L<not working|https://code.google.com/p/selenium/issues/detail?id=3604>.
 
-Nevertheless, we decided to implement the function, because eventually one day it will work. 
+Nevertheless, we decided to implement the function, because eventually one day it will work.
 
 In the meantime, there are workarounds that can be used to simulate drag and drop, like L<this StackOverflow post|http://stackoverflow.com/questions/29381233/how-to-simulate-html5-drag-and-drop-in-selenium-webdriver-in-python>.
