Multi-step keyboard process:

While focused in Calibre:
Press (I believe it's called) the Menu key (key to the right of the right windows button) to open (what I think is called?) the context (=to right click of the mouse) menu
Down arrow to View
Right arrow to get to that menu
Down arrow to first topmost entry

I know, too many steps!

(another mouse hater)

(I actually started this before the first reply LOL)

(You could actually move View to the top of the Context menu if you so desire... less 'downs'!)
