Lesson 49: Tweaking, Shoulder Squeaking and Component mode blues!

I fully understand the usage of weighting and how he goes about weighting. I don't think I'm one for painting, but who am I to judge? Most of this seems to be based around precision and tedious work. Sounds just like UV mapping! I can't seem to get into component mode. He keeps using F8 and I search but find no simple alternative. The only other answer I can think of would be selecting the individual UVs (carefully). If one isn't careful, they'll end up shifted to all of the other objects within the selection marquis range.
