Keyboard shortcut to change team
To have a single mattermost client connected to several teams is a great feature.
What i find missing is a keyboard shortcut to change team. The other shortcuts are very good and I usually can navigate through many channels and conversations with keyboard only, but when I see that have received in other team, I have to use the mouse.
Perhaps you could add tabs or something similar to the "quick channel switcher" (Ctrl-K) or have a new shortcut to switch teams (e.g. Ctrl-T).
