It is pretty nice, it allows me to browse a page without using the mouse. It gets very addictive actually because you come to a certain point where you even *feel lazy* to grab the mouse to browse the page.... Well, feeling lazy is a bit of an exaggeration... It's more than sometimes I am in the mood to use the mouse, sometimes I would rather keep my fingers on the keyboard.
Anyhow, it doesn't work well all the time though... But here is a command I found very useful for copying and pasting
1. / to search for something
2. i to enter carret mode
3. v to enter visual mode
4. move by j,k to select the text
5. y to yank the text
6. ctrl-v to paste later on...
that's it !
