[Improvement of hyperlink in the "rich text attachment"]
In the rich text attachment editor
(1) make the part of the string be highlighted by dragging
(2) press the hyperlink button on the menu bar
(3) enter a URL
(4) press the Add button
Clickable URL is added to the top position of the attachment.
And the dragging part of string(1) becomes marked gray.
The highlighted part above of the string itself becomes clickable.

(why) Currently, I have realized pseudo feature as follows.....
but, these procedures are very annoying to me.
[ PROCEDURES ]:
After keying in new character string that Ｉ want to clickable to the intermidiate position of the existing clickable URL,
remove all the spelling of the URL except this inserted character string.
Thereafter the remained character string becomes clickable.
