[PyMOL] show surface on pymol

Dear Madem/Sir,

I am a user of Pymol software. Pymol facilitates me a lot during my study. I have a problem and maybe need your help. I want to show surface of a ligand in which there is a methylated lysine. Other residues are OK except the methylated lysine. Could you help me to deal with this problem? Should I install any plugin that can recognize molecules like methylated lysine or anything? Thanks a lot.
