mouse input
Many terminals allow interaction with the current plot using the mouse. Some
also support the definition of hotkeys to activate pre-defined functions by
hitting a single key while the mouse focus is in the active plot window.
It is even possible to combine mouse input with batch command scripts, by
invoking the command pause mouse and then using the mouse variables returned
by mouse clicking as parameters for subsequent scripted actions.
See bind and mouse variables. See also the command set mouse.
