[Chimera-users] How to select whole molecule ?

Hello all, is there any possibility how to select all atoms which belongs to the given molecule ? I mean something which allow me to select whole molecule to which belongs previously selected atom. Unfortunately ZONE selection is not useful here as it allow to select only atoms or residues, not whole molecular structures. Selection by hand/mouse is not possible to use in cases when two or more molecules are very close together. Thanks a lot in advance for advices ! Best wishes, Marek Maly
