Description

Defined in Table 30 of the PDF 1.7 ISO specs, the Tabs key is an optional COSName value under PDPage that defines the tab order of the annotations on the page. The specs define its possible values as: R (row order), C (column order), and S (structure order).

However, from inspecting PDF files created by Acrobat it seems that another value can be used, namely "W", when the form's author specifies the tab order manually. See attached file.

A getter/setter for this value is missing from the PDPage implementation. Also, the "Tabs" key itself is missing from the COSName enum and should be added.
