how do i attach emails to a new composed email? ie from a label/folder.  in outlook this was done by 'attach item'.....

You can select the text of a message, including the header information, and use the standard Copy (Ctrl C) and Paste (Ctrl V) commands to insert it into your message. If you want to attach a previous email, you can do that using the print command:

1) Open the message you want to attach, and choose the Print command
2) A new HTML copy of the email is generated & the Print dialog box shown - click on Cancel to close the Print dialog box but keep the copy of the email on screen
3) Save the HTML file - you can do that by right-clicking on the page
4) Attach the HTML version of the email to the message as required
