[chimerax-users] Coloring charged amino acids

Consider this: open 1pgb fromDatabase pdb format mmcifstyle sphereshow atoms 1. What is the command to hide all water? 2. How do I color charged amino acids, leaving uncharged one a neutral color (such as white)? I was hoping there was a menu item or command that would do something similar to this: color all whitecolor :lys,arg bluecolor :glu,asp redcolor :his lightblue without having to type all those commands. FirstGlance in Jmol and iCn3D have "one click" ways to do this, but I don't see one in ChimeraX or MolStar. Thanks, -Eric
