([neomutt.org](https://neomutt.org/guide/reference?utm_source=openai))\n- To mark a **thread** (all messages in a thread) for deletion, press `^D` (Control-D). ([neomutt.org](https://neomutt.org/guide/reference?utm_source=openai))\n\n### Delete/undelete tagged messages\n- `;d` will delete all **tagged messages**. ([dataswamp.org](https://dataswamp.org/~solene/2019-04-23-neomutt.html?utm_source=openai))\n- `u` unmarks a deleted message (undo). ([realcaptainsolaris.github.io](https://realcaptainsolaris.github.io/redbook/linuxbook/neomutt/?utm_source=openai))\n\n### Actually remove the marked messages from mailbox\n- Press `$`. This executes the `<sync-mailbox>` command: it **writes** changes (i.e. deletion marks) back to disk or IMAP server. The deleted messages are then purged. ([dataswamp.org](https://dataswamp.org/~solene/2019-04-23-neomutt.html?utm_source=openai))\n- Whether you are prompted for confirmation depends on the `delete` variable:\n  - `set delete = yes` \u2192 automatically purge on sync/quit. ([neomutt.org](https://neomutt.org/guide/reference?utm_source=openai))  \n  - `set delete = no` \u2192 keep messages marked for delete until manually deleted. ([neomutt.org](https://neomutt.org/guide/reference?utm_source=openai))\n\n---\n\n## \ud83d\udd01 Reindexing / Syncing Mailboxes\n\nWhen you want to \u201creindex\u201d or force NeoMutt to see external changes (new mail delivered outside NeoMutt, IMAP flag changes, folder modifications made via other clients, etc.), you can:\n\n### Use the `sync-mailbox` command\n- Press `$` in the **index** menu. This is bound by default to sync and write changes. It causes NeoMutt to refresh its view of the current mailbox and \u201cflush\u201d deletions. ([neomutt.org](https://neomutt.org/guide/reference?utm_source=openai))\n\n### Close & reopen mailbox\n- Use `c` to `change-folder` then re-open the same folder. This can help when NeoMutt is caching state and needs to rescan. ([dataswamp.org](https://dataswamp.org/~solene/2019-04-23-neomutt.html?utm_source=openai))\n\n### Delete or reset header/message caches\nIf something with indexing seems corrupt (wrong counts, tea-cup, headers mismatched etc.):\n\n- Header caches are stored in directories governed by your `header_cache` setting; message bodies in `message_cachedir`. You can delete these cache files while NeoMutt is not running. On next startup, NeoMutt rebuilds them. ([neomutt.org](https://neomutt.org/guide/advancedusage?utm_source=openai))\n\n---\n\n## \u2699 Helpful Configuration Settings\n\nHere are options you may want to control via your `~/.neomuttrc` (or `neomuttrc`) file:\n\n- `set delete = yes` or `no` \u2014 whether NeoMutt automatically purges messages marked for deletion on sync/quit. ([neomutt.org](https://neomutt.org/guide/reference?utm_source=openai))  \n- `set mbox_type = Maildir` (or mbox, MH etc.) \u2014 format of local mailboxes; can affect how sync/new-mail detection works. ([neomutt.org](https://neomutt.org/guide/advancedusage?utm_source=openai))  \n- `set mail_check_stats = yes` \u2014 periodically recalc unread/total counts; helps keep sidebar/new mail info accurate. ([neomutt.org](https://neomutt.org/guide/advancedusage?utm_source=openai))\n\n---\n\nIf you want, I can also walk you through setting up key-bindings or macros to automate clean-ups (e.g. auto-syncing or purging deleted messages on quitting). Do you want that?"
