To be able to

When you are trying to proofread your writing for clear, accurate, and correctly punctuated sentences, it is a big help to be able to spot verbs and their subjects. These quick hints will help you find the verbs and the subjects of your sentences.

I understand the above completely but want to know the use of "to be able to". I am really confused by "to be" here? I know the meaning of the sentence when I read but unable to use in my own writing. I know infinitive can be used adjectivially or adverbially.
