Navigation Granularity

The unit of text movement when navigating through content—typically character, word, sentence, line, or paragraph level. Screen reader users must select their desired navigation granularity before moving through text, and the choice significantly affects editing efficiency. Research shows that word-level granularity is overwhelmingly preferred by blind users for text editing tasks, as it balances precision with speed. Switching between granularity levels in traditional screen readers requires multiple interactions with the rotor control.
