`/agent` cannot get out of selected mode?

[scaryrawr]

Describe the bug

When you switch to a custom agent mode, there doesn't appear to be a clear way to get back to the "default" agent mode.

Affected version

0.0.370 Commit: 5188822

Steps to reproduce the behavior

1. Type /agent
2. Selection an agent
3. Type /agent
4. Try to select the "Default" mode.

[Workaround]

Create a custom "Agent" mode.

Expected behavior

There should be a Default or Agent mode to switch to when I type /agent to get out of the custom agent mode if I'm not already in the default mode.
