Make better keyboard controls

I’m using a Chromebook with a touchpad mouse, and it’s very hard to move between boxes. For instance, the scrollbar on the right side of each box is hard to activate - I have to guess where it is by sliding the cursor around. On the doc list, it doesn’t always appear at all. While editing, I have to down-arrow to move through the text as I’m reading because the page down button sends me to the next box e.g. it sends me from chapter text to the bible, instead of to the next screen of text.
