Hi! For context: TIOCLINUX's TIOCL_SETSEL sub-code has another layer of sub-operations, called "selection modes" (even though not all of them actually deal with the mouse selection). Going forward, the CAP_SYS_ADMIN requirement will be different for some of these selection modes, which promted me to at least list the different selection modes with a short description. I am leaving CAP_SYS_ADMIN documentation as it is for now and will send another patch once these semantics are finalized [1].
