When the reader is opened, Ctrl + and Ctrl - doesn't work. In the toolbar, for the big + and - icons the tooltip says "Control plus" and "Control minus".
I tested on more computers. When the Reader starts inside the web browser, here also doesn't work.
After clicking in menus or clicking the toolbar buttons (I wasn't able to discover exactly when), the Ctrl+ and Ctrl- starts working.
