Now, I'd like to implement the function: moving the cursor with letter keys. I find that I end up to use the range functionality. So I have to caculate the content of a range, and to identify the position of a range. It works though.
Certainly, I can move the cursor with the arrow keys easily and quickly. My question is why I cannot move the cursor like the arrow keys' doing in rich formatting textarea. I am confused by the implementation of arrow keys. How can I implement moving the cursor easily in my functions.
Thanks in advance.
