Hello Friends,
I have this  below code.

<apex:page standardController="Account">
    {! Account.Name }
    {! Account.Phone}
</apex:page>

I can comment the code by standard way (" <!-- This is commented part --> ") which I can do with few clicks.

Is there a way using the keyboard shortcut to do so? MS Visual Studio has it. May be the Eclipse too, although not sure.

Please help, thanks!
