Accessibility Functionality for TAP
There are the five Accessibility Items:
- Keyboard Shortcuts
- Tabbing through fields
- Screen Reading using NVDA
- Visibility (Color)
- Hover Text (ToolTips)
Keyboard Shortcuts
- Screen functions are able to be initiated via keyboard
- context menus
- action menus
- modals
- All elements initiating an action (e.g. Buttons but typically not entry fields) have an assigned shortcut or are specifically excluded
- When the shortcut is entered, the page performs the button's action in the same manner as clicking the button itself
- regardless of which element is currently in focus
Tabbing Through Fields (Focus Tracking)
- All user elements required to operate the page are in the tab order
- Page structural elements are in the tab order
- Sequence proceeds generally top to bottom and left to right
- Hidden items are skipped
- Page relocates (scrolls) to display element if necessary
- Informational elements are included in tab order if selecting them changes their display
- Focus is clearly visible on every element
Visibility (Color)
- All screen elements are visible via contrast alone
Hover Text (Tool Tips)
- Font size is adequately large
- Contrast is clear
Screen Reading via NVDA
All visual elements are identified verbally
- by mouseover
- by tab (focus)
