Autopickup

Autopickup is an option, on by default, that specifies that your character automatically picks up any item on the square he/she moves onto.

While this may seem convenient, it often causes problems, particularly with heavy or dangerous items. However, in most cases these problems can be mitigated by proper application of the pickup_types and pickup_burden options.

To toggle autopickup, you can select it from the Options menu or press '@'.
