**Which product are you using?**
Pdf.Js Express Viewer
**PDF.js Express Version**
8.2.1
**Detailed description of issue**
I want to catch mouseMove events for all words on PDF file itself.
I am wondering that, while using viewer of [pdf.js.express](http://pdf.js.express/), are there any possibbility of catching events when mouse hovered a word in PDF File?
If doubleclicking on word can catch event and highlight that word, why not possible to catch hovered word.
I want to catch hovered word itself.
**Expected behaviour**
Console.Log ( HoveredWord)
**Does your issue happen with every document, or just one?**
This is kind of feature i am looking if it is exists or achivable

Hey there,
Right now, PDF.js Express does not support catching a word hover. However, I will add it to our backlog and we can investigate implementing it when we have time.
Thanks!
