Yes Freeze-Panes

in Excel 2010 shortkey is Alt W+F+F

To freeze row:

• Select the row below the row(s) you want to freeze.
• Click the View tab on the Ribbon.
• Select the Freeze Panes command, then choose Freeze Panes from the drop-down menu.

The rows will be frozen in place, as indicated by the gray line. You can scroll down the worksheet while continuing to view the frozen rows at the top.

To freeze columns:

• Select the column to the right of the column(s) you want to freeze. In our example, we want to freeze column A, so we'll select column B.
• Click the View tab on the Ribbon.
• Select the Freeze Panes command, then choose Freeze Panes from the drop-down menu.

The column will be frozen in place.
To unfreeze rows or columns, click the Freeze Panes command, then select Unfreeze Panes from the drop-down menu.

If you only need to freeze the top row (row 1) or first column (column A) in the worksheet, you can simply select Freeze Top Row or Freeze First Column from the drop-down menu.
Hope it helps.
