Add KB shortcut to read or read whole page

[ccombe]

some sites for online book reading e.g. O'Reilly.com, when I select text and right click to go into the read option, it deselects the text and hides the menu option.

Could we have an option to read the main text on the body or the ability to highlight text and then execute the read via a keyboard shortcut.

For reference, the read aloud chrome plugin allows this (read whole page) but doesn't support the GoogleWavenet voices ;)
