[Chimera-users] How to select solvent molecule by residue number ?

Hello, it seems that if some amber trajectory but also PDB containing solvated structure/s is loaded into Chimera, there is impossible to select by residue number (using command SELECT in command line or by dialog SELECT->ATOM SPECIFIER) any solvent reside (at least in case of WAT solvent). Am I right ? Perhaps it is possible but maybe with some more complicated command than the usual select :N where N is the residue number. Thanks in advance for any comments ! Best wishes, Marek PS: I am using alpha version from 18th November, but I remember this problem also from previous versions.
