Default value
'Caption' (this is a placeholder default value - you will need to set a caption).

Single-quoted text or the name of a multilingual text variable (the corresponding ellipses button in the property sheet can be clicked to choose one from a list).
If you do not want any caption displayed next to the checkbox (for example, when it is used in a list) you may specify an empty string by specifying two quote marks with no contained text.
