Button reaction depending on the x-coordinate

I need to show some boring tables (some dates, some number and some text; no images) with a lot of boring details. Imagine your bank statement.

On mobile, I'll have to use multiple lines for each entry. Fortunately, this means that the entry is big enough to work as a button.

Unfortunately, I'd need two or three buttons per entry, for actions like

  • show even more details (leading to a new page)
  • mark as read
  • a menu for everything else

Obviously, adding them would take up a lot of space (currently, the users can see about eight entries at once, which may be fine; adding buttons would reduce it to maybe a half).

So I'm thinking about making the entries react differently according to where they get touched, e.g.,

  • left third ⇒ mark as read
  • middle third ⇒ show menu
  • right third ⇒ show more details

Obviously, the user will must some help the first time they use it.

  • Is this a good idea?
  • Are there already some well-known apps doing something similar?
  • Is there a simple and compact way how to visually indicate this functionality?

Explanation

Imagine my entry looking like

          SOMETHING HERE                            22.30         
Lorem ipsum dolor sit amet, consectetur adipiscing  02.12.2019    
elit, sed do eiusmod tempor incididunt ut labore et               
dolore magna aliqua. Mollis aliquam ut porttitor    WOW!

and three transparent buttons laid over it like

LLLLLLLLLLLLLLLLLLLLLMMMMMMMMMMMMMMMMMMMMMRRRRRRRRRRRRRRRRRRRRR    
LLLLLLLLLLLLLLLLLLLLLMMMMMMMMMMMMMMMMMMMMMRRRRRRRRRRRRRRRRRRRRR    
LLLLLLLLLLLLLLLLLLLLLMMMMMMMMMMMMMMMMMMMMMRRRRRRRRRRRRRRRRRRRRR    
LLLLLLLLLLLLLLLLLLLLLMMMMMMMMMMMMMMMMMMMMMRRRRRRRRRRRRRRRRRRRRR
