Grabbing a bit of text from a web page works similarly to selecting text elsewhere on your Android tablet. The difference is that you must long-press the text to start the selection process. (Double-tapping a web page activates the zoom-in feature.)
After long-pressing, you can drag the selection tabs to mark the block or use the Select All command on the Action Bar toolbar to select all text on the page.
Unlike selecting text elsewhere, selecting text on a web page opens access to some special features. For example, you can choose the action bar’s Share command to send the chunk o’ text to another app, send it in an e-mail message, or post it to a social networking site. Use the web Search command to perform a Google search on the selected text.
Touch the Done button on the action bar to cancel the web page text selection. With some web browser apps, you merely have to wait, and the action bar disappears.
Also note that the action bar lacks the Cut command when text is selected on a web page. Use Copy instead of Cut.
