For all of the above, if you would like to see the Scroll larger:
There are 3 ways:
1) Go to the bottom of the page that is showing and click on the right tab in the black section that looks like corners of a rectangular picture frame. (above the 3 parallel dots). (NOTE: IF you do not see this set of icons on the bottom, hover your cursor over the bottom until it appears.) This will enlarge the Scroll to read to full screen size. When you are done reading in full screen mode, press the “escape” (esc) key to return to normal viewing.
2) The full rectangle (to the left of the open frame icon) will display an enlarged view, but not full screen.
3) the slider bar with the minus sign on the left and the plus sign on the right can be dragged to zoom in and out to the size you prefer to view.
To page through the Scroll: Use the arrow on the center, right side of the page to turn the pages forward and the left arrow to go back to a page.
