# ? Symbol -- view brief documentation of a symbol

- Operator: ?

## Description

A question mark followed by a symbol representing a function, type, option name, or package prints a brief, compact list of various ways to use the given symbol.

`? BGG` | -- brief information about the package BGG
`? Tally` | -- brief information about ways to use objects of class Tally
`? betti` | -- brief information about ways to use the function betti
`? Weights` | -- brief information about ways to use the option Weights
`? symbol >>` | -- brief information about ways to use the operator >>
`? HH` | -- brief information about ways to use the scripted functor HH

If the object is defined by the user, brief information about the object and its class are printed.

When using Macaulay2 in Emacs, moving the cursor to each line of the output beginning with '*' and pressing Enter results in showing the full documentation node corresponding to that line.
