Thunderbird-Hilfeforum

In the attached screen shot they are two type of folders - One is yellow and looks like a paper folder and the others are rectangular in shape in different colors (here in res and purple) . I am unable to delete the rectangular folder that appear permanent and I don't even know how it was created as I used the same command "new folder" under the inbox or "new subfolder" under a yellow folder - I hope that this is clear : I want to delete the rectangular folders when needed

As stated in the question, messages older than 1000 days are not deleted (this is a POP server). This is on my Desktop which is my primary PC. I also have a laptop using Thunderbird with "Leave messages on server" but with neither option (Number of days or Until I delete them) checked. The purpose of the laptop settings is that since it is not my primary PC I don't want it to delete anything from the server.

I did quite a few searches and the closest thing I found was another user who had migrated to Thunderbird after using another mail client for years, and it sounded like after they installed Thunderbird, they imported their old emails from the old client and then began using Thunderbird. The explanation they got was that any emails that had not been downloaded from the server by Thunderbird would not have a download date in Thunderbird and would therefore not be subject to the "older than xxx days" setting. That scenario doesn't apply to me because I have been using Thunderbird exclusively for at least 5 years, so all emails on the server that are less than ~1825 days (5 x 365) were downloaded by Thunderbird. All emails older than 5 years have long since been deleted from the server manually.

Either I am misunderstanding the "For at most xxx days" setting or something is not working properly.

I want to customize shortcuts in Thunderbird using tbkeys but I can't find the right command name.

In the description is written: "Most command names can be found in the main command set file of the Thunderbird source code."

But where I can found all/ more/ other command names?

In my case I want to change:

• "Move to previous UI element" (default: Shift + Tab)
• "Move to next main UI area" (default: F6)
