I don’t know of a way to share text combinations, but in Paratext 9 you can share saved layouts, i.e., the arrangement and choice of open windows. Type “share layout” in the Paratext Help Window and you will see the full details.
Of course, the layout will look differently on different sized monitors, and those who share it must have access to the same projects and resources. There will be a notification if a project or resource is not loaded on a particular computer.
Blessings,
