How to disable all Thunderbird keybindings ?

[doublehp]

Trivial question, all in the title: I want ti disable/desactivate all keybindings/shortkeys in Thunderbird.

In E, it happens that the focus does not always work properly (amongst other reasons, because of my wireless mouse that may not always move exactly as it should); if I got too fast, do a mouse move, and start typing, it may happen that what I type sends keystrokes to the main TB window; in which case, entering any couple of word may mark some emails junk, move to next folder containing unread emails, mark them read, apply filters ...

I use very few TB binds; so if it's easier to disable them all, than just keep the ones I need, i don't mind. I use ^ENTER to send.

Since I just migrated to TB3, I need *IN URGENCE* to disable the 'a' shortcut to Archive, because the Archive feature is broken, and may delete some emails.

Thanks.
