Hello Masoud Moghaddam

By default it is available in Studio, however, to keep track of segments you could use comments for example. Are you familiar with this functionality, have you used it before?
Highlight and right-click the terms / segment you would like to add a comment to:

Then it will be visible with a light yellow background, and if you hover over it with the mouse you will see the note added:

Alternatively, there is an app called Wordbird which offers a highlighting tool:
https://appstore.sdl.com/language/app/wordbird/890/

Though I have not used it myself so cannot comment on how this works.

Hope you'll find this helpful. Let me know in case you have further questions.

Best wishes,
Greta

Hi Greta,

Great! Add Comment feature is cool; didn't know it works for highlighting task as well. I hope in next version, the Studio will bring highlighting feature with multi-color support (I guess it would be nice and helpful to highlight some text with one color and some of them with another one for some purposes, e.g, red ones are important text, and orange less important to check or whatever). But currently, I'm comfortable with the Add Comment feature and helps me to mark those text I need to give them color for next checking out easily. Thank you, Greta! 

Have a nice time!

Masoud
