E-mail as PDF in LibreOffice Writer
This item launches the PDF Options dialog, so the user can use the settings to control the exportation of the document to PDF format. This dialog is slightly different than the PDF Options dialog that is launched when you click the Export as PDF item in the Export As sub-menu of the File menu.
The dialog launched from the Send as PDF item has a Send button rather than an Export button. The Export button will launch a dialog to Export the document to PDF. Clicking the Send button launches the default email client with a new message and the document attached to that message.
