I have a multiline edit box. I want the user to be able to enter data on the left side of the edit box up to a certain line. For example,

[text, text, text, text | ]
[more text, | ]



Then hitting tab button shifts the cursor to the other side of this center line so that the user can enter data to the right of this dotted line.

Is this at all possible, and if so, how would go about implementing it?

Any response any one can give me will be greatly appreciated.

Sincerely,
Danielle
