Thank you Noam. I've closed the bug. The behavior was not clear by just reading the documentation.

Thank you for trying. I won't be testing further because the mode is not very helpful for my use case (editing TSV files).

Now that my first question has found an answer, here come my second question.

This mode is the only one along with help to be assigned a prefix function key. F1 for help and F2 for 2C editing. The prefix is mentioned in the very first chapters of the manual and C-x 6 is mentioned at the same level as C-x 4 and C-x 5.

Since the code dates back from 92 I guess it was considered important enough at the time to get that F2 prefix. But is it widely used now ? I'm not finding a lot of references to it on the net.
