[chimerax-users] help with chimerax wildcards

Hi, I am trying to use wild cards in chimerax but they appear not to work. I type the command color @N* blue and get as response Expected a color or one of 'byatom', 'bychain', 'byelement', 'byhetero', 'bymodel', 'bynucleotide', 'bypolymer', 'fromatoms', or 'random' or a keyword All I am trying to do is color all nitrogens blue. Version 0.5 (2018-02-05) running on macOS Sierra v10.12.6 what am I doing wrong? thanks Mike Lawrence
