When creating a new interface a GUID has to be added to the interface definition. The Embarcadero IDE has a shortcut for this Ctrl-Shft-G
Does Visual Studio Code with the omnipascal extenson also have such a shortcut?
There is no dedicated shortcut for creating a GUID for an interface but it's always the first item in the code completion list when requested from inside an interface declaration without a GUID. The default shortcut in VSCode to request code completion is CTRL+SPACE.
