How To Scroll the Pages in Selenium WebDriver

SCROLLING THE PAGES
==================================================================
-------------------------------------------------------------------------------
1)Using JavascriptExecutor interface
//launch the browser
WebDriver driver=new FirefoxDriver();

//create a variable for JavscriptExecutor and assign webdriver varaible
JavascriptExecutor jsx=(JavascriptExecutor)driver;
//scrollDown
//jsx.executeScript("window.scrollBy(horizontal,verticaldown)","");
//vertically scrollUP
jsx.executeScript("window.scrollBy(horizontal,-verticaldown)","");

how can you scroll until the visibility of particular element.

jsx.executeScript("arguments[0].scrollIntoView(true);",elelementName);
-----------------------------------------------------------------------------------
2)scrolling the page using Keys enum
driver.findElement(By.localtor("value")).sendkeys(keys.keyname);
scroll down
driver.findElement(By.tagName("body")).sendkeys(keys.DOWN)

Scroll Up
driver.findElement(By.tagName("body")).sendkeys(keys.UP)
