In Open Office, how do you make the first row of data "scroll lock" so it is always visible as you scroll down?
Select the first row below that which you would like "frozen" and select Window | Freeze.
EDIT: In fact, this works to freeze rows and columns. For example, if select cell C3 and Window | Freeze, then the first two rows and the first two columns will be frozen.
Or do it in one step by putting your cursor in the first cell that you want to allow to change, then click Window > Freeze.
For example, to freeze the first two rows and the first two columns, you'd put your cursor in cell C3 and click Window > Freeze.
