Get the cursor position in TextArea?

Hi,

can I know from the backing code where the cursor in the TextArea is placed? Eg to extract the text that is in front of the cursor, and after it.

Also, is it possible to format a text to be displayed differently than the backend source holds the text? Eg if I have a comma-separated list, can I keep that list in backend with commas, but display it in UI without commas?

Thanks
