Can't figure out how to target manually.

I've tried reading the books and tutorials. I've hunted online for Youtube vids but F me if I cannot figure out how to do this. Most vids do NOT help as people do things off video like calculate speed. Other's don't speak English or just play music while using text.

I've watched wolf play and he brings up all these tools and what not I can't figure out how to bring up. I pull up the book and all I get is warships.. I know there is another book but how do I access it? God I feel so stupid...... Help? Someone point me to a good video to watch on how to do this?

I am using the Commander mod, and the Grey wolves mod. Mainly because that's all that still have working download links.
