I don't know why all commands would become greyed out unless it changed the document to Viewing mode (you can test this via a button at the top right of your screen). But that command by itself wouldn't remove the content from the file.

If all the text has disappeared from the document, there are two possibilities:
1. It is still there but hidden
2. It has been deleted and then the document was saved to make it permanent

What is the size of the file? Is it the same size as an empty document or does the file size imply that it has content?
