The header shows the table no. and has a ? button giving access to the inbuilt help and to the TD menu (when the button is pressed longer).
In the header you will also find the board no. when that has been selected and the entries (the result) on the board.
Note that you can correct mistakes as soon as you spot them by pressing the buttons in the header. See a separate page for details.
The footer is used to navigate between screens. The red, back button should be handled with care as it can lead to strange situations if you go back too many steps. It is, generally speaking, safer to use the green, forward button until you come to the round summary screen from where you can go to reported boards without problems.
Some footers contain a third button leading to another screen. The illustration to the right for example shows the button leading to the analysis of the deal.
