Definition in the specification
Table 189 · Entries in an appearance characteristics dictionary
ISO 32000-1:2008, §12.5.6.19 · PDF page 417 ↗
/CA text string
(Optional; button fields only) The widget annotation’s normal caption, which shall be displayed when it is not interacting with the user. Unlike the remaining entries listed in this Table, which apply only to widget annotations associated with pushbutton fields (see Pushbuttons in 12.7.4.2, “Button Fields”), the CA entry may be used with any type of button field, including check boxes (see Check Boxes in 12.7.4.2, “Button Fields”) and radio buttons (Radio Buttons in 12.7.4.2, “Button Fields”).
Qualifier: Optional; button fields only
