Does what it promises, this feature could be part of the core version of Thunderbird.

This review is for a previous version of the add-on (0.7).

Thanks for your review. Unfortunately this feature won't be added to core Thunderbird, because it is against Mozilla's interface guidelines to use single printable characters as a keyboard shortcut.
