How to pass list of selected files from FM (file manager) to a launcher?

It's ideal to have software launcher and FM that are communicating with each other

so that (for example):

• left mouse click on the launcher icon starts a software or passes list of selected files to it,

• middle mouse click opens FM` new tab with software` bin folder,

• right mouse click opens FM` new tab with software` profile folder.

It's ideal for me. But i'm completely new at Linux and don't know where to start.
