Tip 272 – Quickly attach an attachment to a new email in BlackBerry 10

If you received a file by email on your BlackBerry that you need to attach to another email, rather than download the attachment, save it, and then attach it to the email, go to the new email, select the attachment icon and select the “Hub Attachments” option.
This will display a list of all the attachments on emails in the Hub. Select the attachment you want to send, select the done button and it will be downloaded and attached in one step.
