Too, Also / -도 (Part 2)
In order to use -도 with verbs we must first change the verb to its noun form.
How to change a verb to its noun form
The simplest way to think about this is to add -기 to the verb stem.
보다 = to see
보 + -기 = 보기 = to do the acting of seeing
보기도 하다 = to also see, to even see
먹다 = to eat
Noun form: 먹 + -기 = 먹기 = to do the act of eating
먹기도 하다 = to also eat, to even eat
If a verb already has 하다, then just add -도 after the noun.
