At its core, "viewerframe mode full" is a command or a state variable used within media player APIs (Application Programming Interfaces) and 3D viewer libraries.

  • Multi-page navigation: continuous vertical scroll or single-page snap; keyboard PgUp/PgDn, arrow keys, or gesture for page jumps.
  • Document reflow for text (EPUB/HTML): toggle reflow on/off; reflow respects user font-size and line-height preferences.
