Set Marker Set a marker in the Text Viewer to keep your place. You may set up to 10 markers, 0 to 9. If a marker has been set, its number is checkmarked on the sub-menu here. To mark a line, first put the cursor on the line. Move to the line with the cursor keys or click on it with your mouse. Then click on the Set Marker menu, and on the sub-menu, choose a marker number 0 to 9. If you click on a marker 0 to 9 that is already checkmarked, the marker is reassigned to the line your cursor is currently on. See Go to Line on the Text Viewer Search Menu.
