hi all
after reading the agenda buffer section in the manual i still cant make sense of the bulk remote editing commands and specifically the mark vs mark for bulk.
my use case is simple , i want to mark a bunch of entries like in dired and execurte del/archive/change state etc

using `m` to mark i can see that the entries are marked but cant seem to understand how to then delete/archive these marked file.
also what is M-m for if i can mark with `m`?

thx so much

Z
