Although keyboard-only access is almost always possible, it is not particularly usable. Access barriers associated with the Windows 95 operating system and many Windows applications render the keyboard interface less than usable. Efficient use of the keyboard interface depends on the ability to immediately spot the focus and pick out important information. Dialog box focus is shown by a faint dotted line around the perimeter of the object. The focus indicator should be unambiguous and conspicuous.
Some dialog boxes are visually busy.
In some dialog boxes, fonts are inordinately small and underlined access keys are hard to see. The Microsoft Windows Guidelines for Accessible Software Design recommends that developers avoid hard coding font sizes smaller than 10 points, but even this modest standard is often disregarded. The insertion point in word processors and text editors is hard to see. The Accessibility status window, which shows MouseKeys, StickyKeys and FilterKeys states, is too small to provide useful information to anyone with less than perfect vision. Furthermore, the StickyKey indicator does not differentiate between latched and locked states.
