Tab completion for operations should show low-level operations

If you cd into a resource and hit tab, you see the list of high level commands.

If you type : and then tab, you get the low level commands.

The latter is perfect, but the former is unintuitive. I suggest hitting tab from a resource shows the high level commands, plus the low-level commands prefixed by ":". So the user sees all commands with the correct thing to type to invoke them.
