Configuration

The tooltip is displayed by use of a plain <A> tag. Example:

The "showTooltip" function is called when someone moves their mouse over the link. This function takes two arguments:

event = Always the first argument
"Text of tooltip" = The text you want to be displayed in the tooltip

The "hideTooltip" function hides the tooltip when the user moves the mouse cursor away from the link
