Selecting the exposure not the .tvg drawing name on the timeline

In this link:

it talks about “The Timeline view allows you to read your timing from left to right. It represents the scene’s elements in their simplest form. You can also see the layers and their names, as well as the drawing’s exposure. The drawing name is displayed when you place your pointer over the drawing’s exposure.”

For some reason, my timeline keeps highlighting this drawing (1 frame) rather than selecting the entire exposure when I animate. I know it’s probably a simple button I pressed, but I wish to change it back. I want to move the entire frame + exposure, not just the drawing.

Thank you.
