:focus

Arguments: &optional process

With no arguments, print the process on which the listener process is focused. Otherwise, focus on process, arresting it for debugging if :debugging is not already on process's list of arrest reasons. Focus on the listener process if the argument is :listener. Note that the listener process is not arrested.

:focus keeps a stack of processes on which the user has focused. When the current focus is moved from a process by using the command :unarrest, this stack is used to determine which process will become the focused process. The listener will become the focused process if no other processes are on the stack.

The minimal abbreviation of :focus is :fo.
