 Pointing Device is a generic name for a feature intended to be generic: moving the system pointer around.  There are certainly other options for it - like mousekeys - but this aims to be easily modifiable and hardware driven.  You can implement custom keys to control functionality, or you can gather information from other peripherals and insert it directly here - let QMK handle the processing for you.
