Issue Summary

On the "Create pull request" page, the instructions to show the hidden lines are unclear for the users of a keyboard and a screen reader.

Steps to Reproduce

2. Navigate to the table in the "Diff" tab.
3. Observe the instructions provided for expanding/showing the hidden lines.
4. Observe that the instruction to perform that action is not appropriate.

Screenshot

Actual Results

When screen reader and keyboard-only users navigate to the end of the table, there is a "lines hidden. Shift + click to show all lines" instruction to show the hidden lines in the table. However, this instruction is not clear and appropriate for the users of a keyboard and a screen reader.

This might disadvantage the users of a keyboard or a screen reader. That the hints are inappropriate, may confuse or mislead them.

Expected Results

Avoid specifying inappropriate instructions for performing any action. Make sure that you provide clear and comprehendible instruction so that they can be easily understood by all users. In this scenario, make sure that you provide correct key combinations as a shortcut to expand the lines.

Workaround

Currently there is no known workaround for this behavior. A workaround will be added here when available
