+
+#### All together:
 
 You can see how a cursor color and a cursor line color change when I switch modes/operators: Green for "insert" mode, blue for "change" operator, red for "delete" operator, orange for "yank" operator,
 violet for "visual" mode, cyan for "replace" mode. Moreover, when you switch windows you can see how those colors changed for inactive window.
