Added function: display and run Macros

If you display and run macros than many of the feature requests would be taken care of. Suggest two letter named macros at the head of the list that way users could quickly execute functions from the screen: Light ON/OFF LN/LF Home XY HA Home Z HZ

No files, tests, or entry points are named. Start by locating the screen code and any existing macro or function-execution handling, then define how two-letter macros are displayed and triggered; done means the listed examples can be selected from the screen and run reliably.
