Testing this awesome glitch someone else posted in another FO4 video, basically you grab and item, and hold it in your "hands", then backup towards a building or wall etc, and as you press the back button, you climb up the wall, just make sure not to fall as without wearing PA, you might break your legs.
It's pretty cool though and helps you reach high places, as long as the wall is sheer and not bumpy or has anything in the way you can climb really tall buildings this way.
