The most useful Thunderbird shortcuts

The Thunderbird email client is a popular open source desktop program that is used by millions for sending, receiving and managing emails. The program supports a number of keyboard shortcuts that are mapped to specific functionality. While it is possible to use Thunderbird using the mouse exclusively, keyboard shortcuts may speed up certain operations.
This guide lists the most useful shortcuts for the Thunderbird email client; most useful in regards to improving productivity by speeding up workflows. Thunderbird displays some of the supported keyboard shortcuts when you open menus.
Thunderbird keyboard shortcuts
Modifier keys are the Ctrl-key on Windows and Linux, and the Cmd-key on Mac OS devices. This guide uses Ctrl, and Mac users need to replace it with Cmd whenever it is used to make the shortcut work on their devices.
- Create a new message -- Ctrl-N
- To write a new, blank, message, use the shortcut Ctrl-N. The shortcut Ctrl-M is also mapped to creating a new message.
- Forward a message -- Ctrl-L
- You can forward the selected message by using the keyboard shortcut Ctrl-L; this works with multiple messages as well.
- Add labels to messages -- [0..5]
- Use the shortcuts 0, 1, 2, 3, 4 or 5 to add labels. These set the label to None, Important, Work, Personal, ToDo, and Later respectively.
- Mark as Junk -- Ctrl-J
- The shortcut Ctrl-J marks the selected message or messages as junk. Use Shift-J to mark the selection as "not junk".
- Go to next unread message -- N
- Open the next unread message in the mail folder by tapping on the N-key. Thunderbird suggests to switch to the All Mail folder if there are no unread messages anymore in the folder. To go to the next message instead, use F, and to the previous B.
- Send the message -- Ctrl-Enter
- Use the keyboard shortcut Ctrl-Enter to send the selected message immediately. You may also use Ctrl-Shift-Enter to send it later.
- Reply to message -- Ctrl-R
- To reply to the selected message, use Ctrl-R. If you want to reply to all recipients, use Ctrl-Shift-R instead.
- Get new messages -- Ctrl-T
- Retrieves new messages for the active account. If you want to retrieve new messages for all accounts, use Ctrl-T instead.
- Send and receive all messages -- Ctrl-F5
- The shortcut checks all mail servers for new messages to retrieve them, and sends all messages that have not been sent already.
- Display the message source -- Ctrl-U
- If you need to analyze a message, viewing the source is most helpful. Use Ctrl-U to display it.

You said that Outlook isn’t your main email client, so which is your main one?
I think its thunderbird
It is Mozilla Thunderbird.
Awesome! This actually solved my problem… what a stupid bug.
If this is the same bug that I’ve encountered, there may be another fix: (1) hover over open Outlook item in Taskbar, cursor up to hover over Outlook window item, and right-click; (2) this should give you Restore / Move / Size / Minimize / Maximize — choose Move or Size; (3) use your cursor keys, going arbitrarily N/S/E/W, to try to move or size the Outlook window back into view. Basically, the app behaves as though it were open in a 0x0 window, or at a location that’s offscreen, and this will frequently work to resize and/or move the window. Don’t forget to close while resized/moved, so that Outlook remembers the size/position for next time.
THANK YOU Claude!!! I could get the main window to launch but could not get any other message window to show on the desktop. You are my hero!!!!
Solved my issue! 6 years later and this is still problem…
Fantastic. Thank you. Size did the trick.
This solved my Outlook problem, too. Thank you. :)
Thank you so much, this started happening to me today and was causing big problems. You are a life saver, I hope I can help you in some way some day.
You are a god – thank you!

Yah…thanks Claude. I’ve been having the same problem and tried all the suggestions…your solution was the answer. It had resized itself to a 0/0 box. Cheers

Thanks a lot. I was facing this issue from past 3 week. I tried everything but no resolution. The issue was happening intermittently and mainly when I was changing the display of screen ( as i use 2 monitors). The only option i had was to do system restore. But thanks to you.

This problem was faced by only one user logging to TS 2008 r2 using outlook 2010.The issue was resolved.

Great tip. Thank you!!!! If it helps, I had to use the Control Key and the arrow keys at the same time to bring my window back into view. Worked like a charm.
