In addition to using

   :push <query>

you can also use

   :exec query

I don't remember the difference, if any other than the syntax, 
off-hand.

You can query the value of a variable by preceding its name with a 
question mark in the set command, like this,

   :set ?pager

or by starting a set command, then typing a tab after the equals 
sign.  For example, type this,

   :set pager=

then hit tab.  Note that mutt has variable-name-completion on the 
command line, too.  Just type the first few characters of the 
variable name, then tab.  If there is more than one match, 
successive tabs will cycle through the alternatives.
