My question is: If I'll take an action in my Thunderbird client (such as deleting messages from the Inbox folder), it will effect my default GMail account?
Yes, if you set up the account with IMAP, both will be synchronized. Your Thunderbird client will display every Gmail label as a folder, thus moving messages in a folder means "applying a label" in Gmail. All changes you make are almost instantaneously visible in the web client too.
If I'll delete message XYZ from Thunderbird, I won't see the message in the default GMail web client? (mail.gmail.com)
If you delete a message in Thunderbird, it will be moved to a folder you set (preferably the Gmail Trash folder). Because of that you will still be able to see it in the Gmail web client, under "Trash".
In order to completely delete messages, you will have to clean out the GMail trash, of course.
Though new messages (after the complete setup and integration of Mozilla Thunderbird with GMail), will be completely deleted from my account.
What exactly are you meaning with new messages? Note that there is nothing changing when you use Thunderbird – messages will still land in your inbox.
How can I effect old messages as well?
What do you mean with "effect"? You will be able to see all your messages in the folders once you set up Thunderbird, which means you can always use its search function and batch move/delete messages, et cetera.
For more details about how to set up Thunderbird, see the following pages:
You can always do it with its Alt code: Alt+96 for the grave accent, and Alt+126 for the tilda.
If you want to use those accents in combination of other letters, you have mainly 3 solutions:
- Use another key combination to change your layout/input language,
- Learn by heart all alt codes for those accentuated letters,
- Use a Autohotkey script to remap your keys to avoid the ` one.
