Option to quickly create a comment block

The only feature that I have missed since I switched to Resharper++, from VisualAssist, are the following intuitive shortcuts. I wish Resharper could have the same feature

1) If a text block is selected, then / will directly prepend // in front of each line, to transform the block into a set of commented lines
Like:
 

if (foo)
    callSomething();

to

// if (foo)
//    callSomething();

2) If a text block is selected, then * will directly surround the code block with /* (…) */

if (foo)
    callSomething();

to
 

/*
if (foo)
    callSomething();
 */
