If there is already a gray box around the element, and you just want to change the tag (e.g., changing a heading level), try clicking on the tag in the in the top-left corner of the box. It is sometimes difficult to select exactly the right area, but it is a little easier if you try drawing a box that is slightly larger than the content. To add or change a tag, use the crosshairs ( ) to draw a box around content you want inside this tag. You cannot undo changes made with the Reading Order tool.
