the scroll bar function in the VR Comp Editor pane

Dear All,

Could you tell me how to enable the scroll bar function in the VR Comp Editor pane/tab?

I have some .aep file that have more than four "Edit 1" on each. It's invisible fifth "Edit 1" in the pane due to the display resolution and the screen size(13"). I'm looking for how I can re-edit the fifth or sixth "Edit 1". Please tell me.

Thank you.

Best regards,
