+This block creates a variable check box. \
+Leave the label blank to use the variable id as the label.
+
+A check box selects between two values of similar type. \
+Te values do not necessarily need to be of boolean type.
+
+The GUI hint can be used to position the widget within the application. \
+The hint is of the form [tab_id@tab_index]: [row, col, row_span, col_span]. \
+Both the tab specification and the grid position are optional.

+This block creates a variable with enumerated options. \
+The gui widget is implemented as a combo box or radio button group. \
+Leave the label blank to use the variable id as the label.
+
+Choose the number of options available to your chooser. \
+When the label is left blank, the option will be used as the label. \
+Set the number of options to "list" to enter a single list of options and labels. \
+When the labels is an empty list, the options will be used as the label.
+
+The GUI hint can be used to position the widget within the application. \
+The hint is of the form [tab_id@tab_index]: [row, col, row_span, col_span]. \
+Both the tab specification and the grid position are optional.
