If IsTextEditor is true, then it means that the function is being used to edit a text by editing one line of the text at a time. Doing soIn this case, since shifting a line to the left or right should not only cause the editing line to be shifted, but also the rest of the lines in the text. To do this , io_edit should let the calling function take care of shifting instead of doing it, by itself. Since shifting essentially means modifying “*offset”, if when “IsTextEditor” is true, then at anytime and that there are times when you find that “*offset” needs to be modified, you should terminate the function instead and . With termination, the function should return the terminating key.
