Is it possible to retrieve the index into a text area that the cursor is at using the keydown event?

Yes, it is.

textarea.addEventListener('keydown', function (){
    console.log(textarea.selectionEnd); //The position of the cursor. If something is selected, then the position of the end of the selection.
}, false);

This function won't work for IE. In IE you'd have to use document.createTextRange().

I know it works in Firefox, Safari. Does it work in IE? – Akhil Dec 22 '11 at 17:54

@Akhil As I've said in the answer, no, it won't. – Some Guy Dec 22 '11 at 17:57

Please refer the below link for the implementation. You can call the getCaret function on your keydown event to get the index of the caret:
