Editing Mouse keys (section)

==History==

Historically, MouseKeys supported GUI programs when many [[Computer terminal#Graphical terminals|terminals]] had no dedicated [[pointing device]]. As pointing devices became ubiquitous, the use of mouse keys narrowed to situations where a pointing device was missing, unusable, or inconvenient. Such situations may arise from the following:
*precision requirements (e.g., [[technical drawing]])
*[[accessibility|disabled user]] or ergonomics issues
*environmental limits (e.g., vibration in car or plane)
*broken/missing/unavailable equipment

In 1987, Macintosh Operating System 4.2 Easy Access provided MouseKeys support to all applications. Easy access was (de)activated by clicking the {{Key press|shift}} key five times.{{citation needed|date=August 2024}}

By the early 2020s, with [[Graphics tablet|graphics tablets]] becoming more common, a configuration change may be required before enabling MouseKeys.{{citation needed|date=August 2024}}
