Key Mapping for mouse click

Do you know what the key mapping is for moving from the header to the lines on a screen in 8.11? In the fat client you just need to press 'Enter'. But on the web you can either use the mouse or tab through the remaining fields to get to the lines. We want to avoid both these options. Is there a corresponding key mapping that can be used? <font color="blue"> </font>
