click on the far right + sign enter next condition eg; Body contains some words

You can add more conditions if required.

close Filter. Make sure your filter name is enabled.

Well I thought about this a bit. Even tried to hash it out.

What I can't get past is that there are perhaps 7 to 10 email lists that I'd like certain, not-too-oft-appearing emails, to be moved for me to view. Sort of a "immediate attention" folder.

So if I see 'firmware_update' in a Celestron List, I want it flagged and moved. If I see firmware-update in elecraft I want it flagged and moved.

And if I see dog-food-recall in that otyher list, I want it flagged and moved.

There are a few other criteria and a few other lists.

I have an email program which recently made changes I couldn't cope with. In That email program I could have a list of items in a filter. One line could have a sub -filter by ctrl-clicking the "+" to add another line ... this would indent and make that next filter only fire if the line above it was satisfied.

Sadly I dumped that program and am back with EarlyBird/Thunderbird as it's a lot more friendly and stable.

What you need to consider is if the first filter moves the mail from the inbox, then it is not there for a later filter to execute upon. SO if your first filter moves messages from the netgear support mailing list to a folder then there is no point of a later filter to move that same mail somewhere else.

Hi Matt: We both "may" be pursuing this different than I originally thought I was asking. If that makes sense.

A single tickler-folder will always be the endpoint for must-read (immediate attention) skimmed emails.

I dunno know how TB/EB works the filtering. Does it take each email and compare it to each filter and cease comparing that email when the first in Boolean True is met (likely)?

Or does it take each filter and look to see if each email fits it?

Well, my Tickler-folder filter is searching for incoming emails which contain facts I want to immediately act upon after morning coffee.

Does this particular email :

    IS NOT not a reply in any thread ie "Re: "
    OR stem from Linux 
       AND mention the keywords they use when a new build is out
   OR stem from Arecibo
       AND mention 144mHz operation
    OR stem from gnupg
         AND mention a new build (in the way/words they do)

IF any above is Boolean True THEN

    move email to Tickler-Folder
    Cease execution of this filter

Otherwise

    (with this email) process next filter in the line of filters made for this       email account

In that 'other email program that keeps crashing now' I could do the above. As I will not use it again for a few years until it's stable here, on my box, I prefer EB and TB. Thus pursuing Email Filters,

For more ambitious filtering, I'd recommend that you look at the FiltaQuilla add-on, and learn how to use regular expressions. I use this to manage Redmire reports.

As Matt has pointed out, the fundamental limitation is that Thunderbird applies filters automatically only to the Inbox. Whilst the Message Filter dialog box allows you to run filters on any folder, this is essentially a manual task and unsuited to automation. A small improvement is to use an add-on that provides a toolbar button to run filters on the current folder. I use this to manage messages which have been automatically moved to Local Folders in order to make private copies independent of the IMAP server, and also to remove old messages from a feed accounts folder.
