1.第一步找到这个文件
2.将下面代码复制替换下图框中的地方font.monospace.cpp=Fixedsysstyle.cpp.32=font:Fixedsys,size:10,fore:#9CDCFE,back:#1E1E1Estyle.cpp.4=font:Fixedsys,size:10,fore:#4EC9B0,back:#1E1E1Estyle.cpp.10=font:Fixedsys,size:10,fore:#DCDCDC,back:#1E1E1Estyle.cpp.1=font:Fixedsys,size:10,fore:#57A64A,back:#1E1E1Estyle.cpp.2=font:Fixedsys,size:10,fore:#007F00,back:#1E1E1Estyle.cpp.5=font:Fixedsys,size:10,fore:#007ACC,back:#1E1E1Estyle.cpp.6=font:Fixedsys,size:10,fore:#FF80FF,back:#1E1E1Estyle.cpp.11=font:Fixedsys,size:10,fore:#DCDCDC,back:#1E1E1Estyle.cpp.9=font:Fixedsys,size:10,fore:#4EC9B0,back:#1E1E1Estyle.cpp.7=font:Fixedsys,size:10,fore:#FF80FF,back:#1E1E1Estyle.cpp.34=font:Fixedsys,size:10,fore:#500000,back:#007ACCstyle.cpp.35=font:Fixedsys,size:10,fore:#FF0000,back:#1E1E1Estyle.cpp.16=font:Fixedsys,size:10,fore:#9CDCFE,back:#1E1E1E
style.cpp.12=font:Fixedsys,size:10,fore:#FF80FF,back:#1E1E1E
3.把此代码也替换掉框选处# vertical edge at right marginedge.mode=0edge.column=80# Specification for text selection and caret lineselection.fore=#000000selection.back=#005EB3caret.fore=#FFFFFFcaret.back=#000000# Color for vertical edge

重启keil，大功告成！
