I can not locate the Safari actions on my Mac Pro laptop. How can I get them?

Thank you. I apologize for asking such a naive question. I had leaped to an incorrect conclusion from too little information. I am building a routine to work with a series of internet screens, and I have been using "Watch Me Do" to discover actions that I could use. I noticed several actions, such as "Press Delete" and "Press 'g' ", and they had the Safari icon attached to them. I had assumed that they were part of a larger set of actions that where part of the Safari group of actions. Most probably I should have asked, where do I find a list of all the actions, and especially the internet actions, such as "Press Delete" and "Press 'g' "?

Where should I look for reading or educational material on writing a routine of actions? What I have found so far is too general.

I am interested in knowing what actions I can use to select the top item in a list of items (documents) listed on a screen, and then how do I modify the text representing that item and place it back into a field. I am sure it is easy and straight forward, I do not know how to do it or how to find information about how I do it. Thank you again for your reply.
