Regarding the tagging of the Notes, the format in which you present the information in your report (such as vertical layout, landscape, etc.) is not a concern.
Regardless of the tagging method you employ, whether it’s hypertagging or TextSearch, the crucial aspect to consider is the sequence in which the Hypertags/Area definition tags are visually introduced.
These tags need to be presented in the same reading order as the report. This means that if your note structure is divided into two or more columns, you should avoid hyperlinking or defining the area for the entire page.
