+# List autocmds Configured For The Current Buffer
+
+Vim itself and many of the plugins you use will configure `autocmd` triggers.
+This are commands that get executed when a certain editor event takes place in
+certain types of files.
+
+A common example is having a tool like `prettier` configured to format the
+contents of JavaScript files when the `BufWritePost` event happens, that is,
+right after the buffer gets written.
+
+You can list each `autocmd` that is configured for your current buffer using
+`:au` and a couple arguments.
+
+```
+:au * <buffer>
+```
+
+The `*` says match against all events. The `<buffer>` filters them down to just
+what is configured for the current buffer.
+
+If you just wanted to know about `BufWritePost` events for the current buffer,
+try this.
+
+```
+:au BufWritePost <buffer>
+```
+
+Or if you want to know about buffer number `4`:
+
+```
+:au BufWritePost <buffer=4>
+```
+
+See `:h :au` for more details.
