Hi Mihael,  
 
Thanks for contacting us. 
 
Yes , you can display confirmation dialog through change event of RTE, when RTE is edited and its value is changed. If you wish you to check for certain keypress and display a confirmation dialog , then you can perform this using keyDown event of RTE. Kindly refer the following code. 
 
@{Html.EJ().RTE("rteSample").ClientSideEvents(e=>e.Keydown("onKeyDown").Change("onChange")).Width("100%").Height("380px").ContentTemplate(@<div> 
        <p><b>Description:</b></p> 
        <p> 
            The Rich Text Editor (RTE) control is an easy to render in 
            client side. Customer easy to edit the contents and get the HTML content for 
            the displayed content. A rich text editor control provides users with a toolbar 
            that helps them to apply rich text formats to the text entered in the text 
            area. 
        </p> 
        <a rel='nofollow' href="https://mvc.syncfusion.com/demos/web/rte/default" >Demo link for RTE </a> 
    </div>).MinWidth("200px").Render();} 
<script> 
    function onChange(args) { 
      console.log(args.value) 
    } 
    function onKeyDown(args) { 
        if (args.keyCode == 17) { 
            var check = confirm("Please click OK for navigation to demo page.") 
            if (check) 
                window.location = "https://mvc.syncfusion.com/demos/web/rte/default"; 
        } 
    } 
</script> 
 
We have attached a sample for your reference, please find the sample at the following location: 
 
For further reference on the available events in RTE, please refer the following UG document 
 
Note: In our sample, we have just displayed a confirmation dialog to show alert before navigating from the anchor link. You can also render our Syncfusion Dialog with required content for this case and show or hide through show/hide methods based on the requirement. Kindly refer to the below UG documentation links: 
 
Let us know if you need any further assistance on this. 
 
Regards, 
Prince
