Help: How to get Label/Title from an item?

Hi

My basic question is how do I can get the label/title of the item that I stand on (No matter if it is inside an addon or regular kodi’s window)

My purpose is :
– Stand and focus on an item (Inside addon, library, etc.)
– Press on a ket and open the subtitles dialog (When Kodi is not on Playing status!)
– Get the title/lable for using it for the “search” action in the subtitles addon.
* If it’s a movie, so it will take the Movie’s title and the year.
* If it’s a tv-show, so it will take the Tv-show’s name, Season number and Episode number

How do I get this title/lable?

Thanks.
