Requirement is to insert cursor at the end of a Rich Text field by click of some button.
Checked and found few lotusscript method such as "GoToBottom" and "GoToField".
Problem with "GoToBottom" LS method-->
This can help in achieving the requirement. It insert cursor at the end of a rich text field. However, this field need to be last field of the FORM.
If there is any additional visible field below this rich text field, then the method will pick that field and will skip rich text field.
Problem wtih "GoToField" LS method-->
This method works fine but it insert cursor at the beginning of rich text field.
If you want to insert any text at end of rich text field, then again you have to manually move the cursor from beginning to end.
