Thank you for your reply.
The way you described is possible, but not very comfortable.
For example: If you just want to copy a short part, e.g. a number or address you have to
- copy the whole message
- mark the parts you want to copy and copy it
- copy it
- mark the whole message
- delete it
- insert the short part you wanted
- write the surrounding text
If you already started to write a message to someone and than decide to include some information of another message you even have to do the mentioned parts in another message or mark manually the parts of the message with the information you want not to share.
have a nice day,
