I use VI mode when using bash and I sometimes find that some of the standard compspec definitions don't do what I want. For example, java doesn't appear to know that you have been able to do java Source.java since Java 9.
Is there a way to get "dumb" expansion when in VI mode. In emacs mode, I understand I can do ESC / and it will expand files without going through the compspec function. But that doesn't work in VI mode (the ESC just ends normal mode).
