I would like to get the definition of a word on any web page just tapping (not opening another tab). This useful  extension is available on desktop Chrome but not on Nexus7 chrome. Whenever I tap a word, it is highlighted and click share icon. Then what appear is an array of icons such as print, and Google translation. Apple i-Pads and i-Phones (OS6) has this word definition extension (automatically attached to the chrome browser). Let's get fix this issue.
