About Mozilla Thunderbird and its shortcuts

Thunderbird is the long-running desktop mail client, and its keyboard covers reading, filing and composing without the mouse, along with the folder and tag commands that make a large local archive navigable.

Shortivo publishes the Windows list. Thunderbird's interface was substantially rebuilt in recent releases, and add-ons can add or override bindings.
