[chimerax-users] Commands not working

Hello, I am new to this program and am learning the commands. However, when I type the commands from the tutorial, they don't work. For instance, when I do "start<https://www.cgl.ucsf.edu/chimera/current/docs/UsersGuide/midas/start.html> Side View" it registers it as an unknown command. Also, when I do the command "color hot pink :lys", it says it does not know what the residue is. Am I missing anything? Thank you for your time. Best, Cobey Heinen
