Issue Summary

General - The element uses device-dependent event handlers and is therefore not accessible by keyboard alone.
Name of the element: Comment link
Location of the element: In the summary table, this link is relevant to #1
Additional details:
A tooltip content appears on hovering the comment link. But keyboard users are not able to get the tooltip as the link uses a hover event to display the tooltip content.

BACKGROUND:
Some people cannot use a mouse due to vision or motor disabilities. Content that can be operated with a mouse must also be made operable with a keyboard. When content is operable through a keyboard, it becomes operable by a variety of assistive technologies such as speech input software, sip-and-puff software, on-screen keyboards, scanning software, and alternate keyboards.
