**When viewing a message, press `h`.** To return to the normal view, press `h` again.

With typical viewer key bindings, `h` is bound to the `display-toggle-weed` function, which controls whether all headers are displayed or whether headers are "weeded". (Under the hood, it toggles [the `$weed` boolean variable](http://mutt.org/doc/manual/#weed) and redraws the display as required.)

To control which headers are displayed or hidden by default, use [the `ignore` and `unignore` configuration commands](http://mutt.org/doc/manual/#ignore).

(The links are to the stable version Mutt online manual, but there should be no significant difference between Mutt and Neomutt in this regard.)
