Problemas con el Speed Grader [Problems with the Speed ​​Grader]

[frivasga]

Cuando abro Speed Grader para corregir una tarea, sólo aparece el trabajo enviado, el cintillo superior con los datos del alumno y el envío, la barra derecha con el espacio para el comentario general, el recuadro de la calificación y los otros detalles; pero no aparecen los iconos para poder corregir: resaltador, poder escoger textos o vocabulario para comentarios específicos, el "lápiz",los colores,etc. Es decir, en realidad no puedo usar la herramienta. ¿A qué se debe esto y cómo puedo solucionarlo? 

Translation from Google Translate:

When I open Speed Grader to correct a task, only the submitted work appears, the top band with the student's data and the submission, the right bar with the space for the general comment, the grade box and the other details; but the icons do not appear to be able to correct: highlighter, to be able to choose texts or vocabulary for specific comments, the "pencil", the colors, etc. I mean, I can't actually use the tool. Why is this and how can I fix it?

Hello,  @frivasga  Welcome to the Canvas Community! The DocViewer annotation tools will display when submissions are in a supported file type. If you have set the assignment for text entry, submissions of the text entry type cannot be annotated, and in those cases, the annotation toolbar will not display in DocViewer. Please read through How do I add annotated comments in student submissions using DocViewer in SpeedGrader?  and https://community.canvaslms.com/docs/DOC-10033-415241392 to learn more.
