These shortcuts work from both the inbox list and thread detail view. The compose editor opens with correct recipients, subject line, and quoted content pre-filled.

​
Inline Reply

When viewing a thread, press r to open the inline reply editor at the bottom. It includes:
  • Pre-filled recipients based on the last message
  • Subject carried over with “Re:” prefix
  • Your signature auto-appended
  • Full compose features (formatting, attachments, AI tools)
To reply to a specific message in a multi-message thread, hover over that message and click the reply icon.

​
Quoted Content

Original email content is included as quoted text below your reply. Quoted content is collapsed by default behind a ”…” indicator — click to expand. You can edit or delete quoted text before sending. In received messages, quoted content is also collapsed to keep long threads readable.

​
Forwarding

Press f to forward. The editor opens with:
  • Empty To field (you choose recipients)
  • Subject prefixed with “Fwd:”
  • Original message content included
  • All original attachments carried over
Add your message above the forwarded content.

Threading
