13. 9. Short Notation

For simple selections, there is a shorter notation. It consists of 3 parts, which are all optional:

: 1. a # followed by a list of molecule names and numbers
: 2. a : followed by a list of residue names and numbers
: 3. a @ followed by a list of atom names

Spaces are not allowed within such an expression, strings are not quoted. It is possible to give a list of such expressions, separated by spaces. This will select all parts, which corresponds to the logical "or" in the full notation.

Expressions in the short notation can be used within expressions in the full notation, they have a boolean value.
