+ * :hi[ghlight] [on|clear|off]   -> enbale/disable stylesheet
+ * :hi[ghlight] {alt style name} -> switch to the alternative stylesheet
+ *
+ * :colo[rschema]                -> list available user stylesheets
+ * :colo[rschema] {styleName}    -> enable the style
+ * :colo[rschema]! {styleName}   -> disable the style
+ *
+ *     {styleName}               -> the name taked away from a CSS-file-name '.css' suffix
