This is more of a usability question. I want to know if there is any recommendation for selection behavior for an application development.
Example: there are objects in the UI you can select. You select 3 objects with holding down "CTRL". Then you release the "CTRL" button and left-click on one of marked objects. Should the other selected objects be unselected? I see this behavior in applications like Excel or any other app where you have "list-objects" you can select. Where does this behavior come from? Anyone knows if this is a standardized behavior? Thank you for your help.
