Console commands insconsistent with help output

This has been ongoing through several versions. The menus all indicate a / is needed before a command but those commands are rejected. Command without the / works.

```

/?

```

The second error is expected as EnrikHawkins isn't currently on the server.

In BDS-18918 Kinga Izdebska said the / was working as intended, but it is not. The help clearly indicates the / is required and it doesn't work. 

He also said the tab function not working was a different issue. Okay, but help text is still wrong and THAT is the issue that is being reported. If they are not intended to work, the help text needs to be fixed.
