A family of Microsoft word processing software products for creating web, email, and print documents.
There is no built-in keyboard shortcut. Neither is the command available for assigning one to it using Word's facility or that of the OS. There are 2 options provided in the UI:
- Right-click one of the selected objects & choose the Group command from there,
- Use the Group tool in the Arrange group on the Shape Format contextual tab,
Another method is to write a macro to execute the Group command but it does have to be written by someone fluent in VBA, it can't be recorded.
