Are these actions considered an use case?

Let’s suppose we are analyzing Facebook.

When you open Facebook you get a list of recent posts, and you can either like and/or add a comment to those post, or you can create a new post as well

So are “List Recent Post”, “Like a Post”, “Comment to a Post”, “Create a new Post” considered use cases?

I am new to use cases, and I really want to learn how to model the right way, thank you.

Yh i believe this is a use case since these actions are prompted by a user. So what i mean is that some one has to press like in order to initiate the operation.

For example if you wanted someone to log out then you would write the use case like the following : “logOut” - you should write like this

hope i helped
