I'm trying to set custom shortcuts to run certain macros (e.g., if a user presses Ctrl+Shift+L, run the load_all_cat_images sub). But I want it to be self-contained in the add-in so I don't want users to have to also then download a 3rd party Windows or Office hotkey manager software.
I know in Excel add-ins and VTSOs there are ways to put in key event handlers. Is there a way someone could show me to insert the same functionality for PowerPoint 2016?
