A developer has the following trigger that fires after insert and creates a child Case whenever a new Case is created.
List<Case> childCases = new List<Case>();
for ( Case parent : Trigger.new )
Case child = new Case(Parentid = parent.id, Subject = parent -Subject);
childCases.add( child );
insert childCases;
What happens after the code block executes?

A.multiple child cases are created for each parent in trigger.new
B.Trigger enters infinite loop and eventually fails
C.Child case is created for each parent case in trigger.new
D.The trigger fails if subject field on parent is blank

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!
