copy partial lines in VI

Question

There are a lot of different ways in which one can yank complete single/multiple lines. Is there a way in which we can copy partial lines in vi, like just 10 characters of the line.

Answer 1

I would guess the most common partial yanks are:

yaw: yank the word the cursor is currently in
2yaw: yank the word the cursor in currently in and the next (2 words total)
ya(: yank the matched parentheses containing the cursor
yf.: yank from the cursor to the next .
y$: yank from the cursor to the end of the line

Any movement keys can be used.
