Hi Danish,

Tabbing to select fields will not work for signature fields, as they require a click so the signature can be drawn.
Tabbing will select text fields and links on the document. If you are unable to use the tab to select text fields, please verify if the same issue exists on our demo: PDFTron WebViewer Demo: JavaScript PDF Viewer Demo
