What are the hotkeys used in this video in Blender 2.69.1? I'm watching a video which appears to be quite old: http://www.cgmeetup.net/home/uv-unwrapping-and-texture-painting-in-blender-tutorial/ 

What I need to know is what the hotkeys he's using do, and what are they mapped to now. Hotkeys such as CtrlA, CtrlJ, CtrlV, AltF, and that's all I can think of right now.   

When I tried using some of these hotkeys or pulling up a menu with one on the menu, they didn't seem to work. Perhaps they don't work with the current version of blender?

By the way: I am using Blender 2.72b. Internet connection where I am is slow ATM so I can't just download the latest.
CTRL + A in object mode with an object selected you can apply the location, rotation, scale. CTRL + J in object mode with at least two objects selected will  join the objects to one object CTRL + V in edit with some vertices or edges or faces selected mode gives a vertices menu ALT + F in edit mode with 4 edges selected fills it with a face (beauty fill).

The hotkeys are the same for version 2.62 and 2.75 so i guess they are the some for 2.72b
