For most of the commands, it did not state that you have to switch to the correct mode to be able to excute that particular command. For example, this is the section on Adding a contact: add in the UG

When I tried adding a contact for the first time, I thus encountered this problem that says "Unknown command" when I typed the command to add a contact while I was in the Dashboard mode

The message only displayed "Unknown command" and it took me quite awhile to realise I had to be in the correct mode (Contact) for the command to work. It would be helpful if the message displayed could indicate if the user is typing the command in the wrong mode.
