In 1974, moving the cursor to the left margin while using Bravo changed its shape to a double-headed arrow to allow for scrolling. Pressing the left or top red button scrolled the content up, and the line next to the cursor went to the top of the window. Pressing the right or bottom blue button scrolled the content down, and the line at the top of the window went down to the cursor. Holding down the middle yellow button changed the cursor to a thumb, allowing for jumping to that percentage of the document with an indicator of current placement.
