I was about to ask how one could select a series of (for example) pictures in a directory as attachments rather than having to 'a' each one.
However, on trying it, I discovered that tagging the attachments and then hitting Return on the last tagged attachment does attach all the files selected with 't'. Good! :-) But, unlike in the index view, tagging doesn't mark the tagged attachments in any way so with a long list and/or if you only want to attach some files from a long list it's a bit awkward. Is this a bug or an enhancement request? I'm running mutt version 2.0.5 on xubuntu 21.10. -- Chris Green
