Text Selection


The Text Selection addon allows marking / selecting parts of text as correct and wrong phrases.

You can work in two modes:

  • 'Mark phrases to select', where you can mark wrong and correct answers,
  • 'All selectable', where all phrases are selectable and you can mark only the correct answers

and two selection types:

  • 'Single select', where you can select only one phrase,
  • 'Multiselect', where you are able to select multiple phrases.
