Media Alternatives Searchable
Group: user-control • Guideline: media-control
Summary in Plain English
Alternatives for media - transcripts and the like - can be searched and queried.
Why It Matters
Search is what makes a long transcript usable for finding one fact, rather than a wall of text to read through.
For each instance of media with captions and / or transcripts:
Check that a mechanism to search the captions or transcripts is available.
Check that a mechanism to search and look up terms in transcripts is available. This can be:
copying and pasting content from the transcript into a dictionary; or
allowing a platform or application dictionary to show a definition of the term.
Example: VoiceOver on MacOS includes a feature to look up terms for what is under a ‘mouse cursor point’
Expected results
#1 and #2 are true.
