Informational content of buttons.

Somehow I wandered into the "People" section, at the bottom of the column, there are navigated / tabernacled navigation buttons, including a button with a long arrow. Seeing her, I was scared. Not that I wouldn’t see the arrow buttons, but I don’t understand what will happen if I press it. I thought that the pages of 5-10 scroll. But no, the button sent me to 1 page of the list. Similarly, being on the first page, a long left arrow sends you to the last page. Finding out about the actions of this mysterious button is very difficult, and I propose to make it more informative, for example, instead of an arrow, write something like "... 1" (for the option when the user is on the first page: "[last page number] .. . "). I think this will help reduce the level of entropy.
