Pro 3.1 - Cannot put line break in annotation

[KeithAddison1]

I'm editing a long existing annotation FC in Pro.  I can select the annotation, hit modify and click in the annotation to add and delete text.  But I can pound the Enter key all day and nothing ever moves.  Is there some special character that will insert a line break or something?

I just want to put the (10300) under the C instead of right of it.

@KeithAddison1  I am glad that stack and unstack are working for you.  However, Enter key should work to insert a line break.  Are you able to add a line break in the Attribute pane?
