Checkpoint 1.9 - Java

Accelerators (shortcuts) observe operating system keyboard conventions

WCAG 1.0 Priority 3

WCAG Guideline 9. Design for device-independence.

Keyboard accessibility options make it possible for people with a variety of limited hand use disabilities to use their computer. If the application software interferes with these options, some users may find their application unusable.

Requirement

Accelerators do not interfere with the operating system keyboard conventions

Recommendation

Do not use keyboard sequences reserved for the accessibility features on your operating system as application defined shortcut keys.

Checking Tool

Once mnemonics and accelerators have been set, test the functionality with the following operating systems's accessibility components enabled:

  • StickyKeys
  • FilterKeys
  • ToggleKeys
  • MouseKeys
  • HighContrast

The first three are available from the Keyboard tab of Accessibility Options from the Windows Control Panel; MouseKeys is available from the Mouse tab; HighContrast is available from the Display tab.
