Coop is a simple, fast, and reliable nostr client for secure messaging across all platforms.
### Pasting into text fields
Click a field and use Ctrl+V (Cmd+V on macOS), or right-click and choose Paste.
Shift+Insert also pastes from the clipboard on Linux and Windows. On Linux,
middle-click inserts the primary selection at the clicked position: select text
in another application first, then middle-click the field. This also works in
the identity import dialog.
