Add more frames between keyframes
This may be really simple but I'm having a hard time finding where in AE menu to achieve this.
Is there any way to add more frames in between two keyframes? For example, in the image below.. If I want to add say 15 frames in between my "Scene 1 - Outro" and the 4s mark for all layers. Is there a shortcut anywhere that will let me position the blue timeline marker in between the two time-code and add more frames to stretch out all the layers below?

Thank you for all the help.
