Using Tab within Text Field

Hi all,

I want to know if there is any way to use TAB key within a text field. I want four space characters to be inserted inside a text field, whenever a user
presses “TAB” button, instead of selecting the object with next tab index.
Can anyone tell me if and how it is possible?

Is someone has a solution, plz feel free to send me privately at:
