Test notes

All tests were carried out with screen reader factory settings. JAWS in particular has a wide variety of settings controlling exactly what gets spoken.

Screen readers allow users to interact in different modes, and can produce very different results in each mode. The modes used in these tests are:

  • Reading Content read using the “read next” command in a screen reader
  • Tabbing Content read using the “tab” key in a screen reader
  • Heading Content read using the “next heading” key in a screen reader
  • Touch Content read when touching an area of screen on a mobile device

In the “What the user hears” column:

  • Commas represent short pauses in screen reader voicing
  • Full Stops represent places where voicing stops, and the “read next” or “tab” or “next heading” command is pressed again
  • Ellipsis … represent a long pause in voicing
  • (Brackets) represent voicing that requires a keystroke to hear
