FWIW  I had what I think is a related problem and came up with a workaround  I wrote a Chrome Extension that did an document execCommand  paste   into a textarea with focus on window unload in order to populate the element with the system clipboard contents  This worked 100  of the time manually  but the execCommand returned false almost all the time when run under Selenium   I added a driver refresh   after the initial driver get  myChromeExtensionURL    and now it works 100  of the time  This was with Selenium driver version 2 16 333243 and Chrome version 43 on Mac OS 10 9   When I was researching the problem  I didn t see any mentions of this workaround  so I thought I d document my discovery for those following in my Selenium focus execCommand  paste   footsteps

This code actually doesn t provide focus   new Actions driver  moveToElement element  perform      It provides a hover effect   Additionally  the JS code  focus   requires that the window be active in order to work   js executeScript  element focus         I have found that this code works   element sendKeys Keys SHIFT     For my own code  I use both   element sendKeys Keys SHIFT   js executeScript  element focus

The following code -   element sendKeys         tries to find an input tag box to enter some information  while  new Actions driver  moveToElement element  perform      is more appropriate as it will work for image elements  link elements  dropdown boxes etc    Therefore  using moveToElement   method makes more sense to focus on any generic WebElement on the web page    For an input box you will have to click   on the element to focus   new Actions driver  moveToElement element  click   perform      while for links and images the mouse will be over that particular element you can decide to click   on it depending on what you want to do   If the click   on an input tag does not work -   Since you want this function to be generic  you first check if the webElement is an input tag or not by  -   if  input  equals element getTagName        element sendKeys         else     new Actions driver  moveToElement element  perform         You can make similar changes based on your preferences
