+This block creates a variable push button. \
+Leave the label blank to use the variable id as the label.
+
+A push button selects between two values of similar type. \
+The variable will take on one value or the other depending \
+on whether the button is pressed or released.
+
+The GUI hint can be used to position the widget within the application. \
+The hint is of the form address@hidden: [row, col, row_span, col_span]. \
+Both the tab specification and the grid position are optional.
