The pushed functions (e.g., ) aren't run immediately: they are stored up and run *after* all the folder-hooks are done. They are stored up in a "stack", like a stack of plates. Each new push adds a "plate" (i.e. function), to the top of the stack. Then, after the folder-hooks have all run, the functions are executed one by one starting with the top "plate". To summarize, the *folder-hooks* are run in the order they occur in your muttrc. But if those hooks use the push command, the pushed *functions* end up being run in reverse order (because the last function pushed is on the top of the stack). This example is fine, because the "." folder-hook runs first setting the default macro. The override for "All Mail" runs second and will overwrite the first macro: # In most folders, pressing L limits to new messages folder-hook . "macro index L '~N'" # In [Gmail]/All Mail, pressing L limits to unread messages folder-hook '^\[Gmail\]\/All Mail$' "macro index L '~U'" However, in this case I have reversed the order of the folder hooks: # In [Gmail]/All Mail, show only unread messages folder-hook '^\[Gmail\]\/All Mail$' "push ~U" # By default, show all messages folder-hook . "push ~A" The push command is run immediately, but the string it pushes is run *after* all the folder-hooks finish. So in the case, you would want the default "." to be run first. Then for "All Mail" you would want the "~U" to be run afterwards. Sorry for the long post, but I hope that helps a rather confusing topic. -- Kevin J.
