*clipboard
*clipboard writes text by default. Use
*clipboard.write or *clipboard.copy for
explicit writes, and *clipboard.read for explicit reads.
All forms delegate to sercrod.clipboard.
Matching n-clipboard forms are aliases.
<button type="button" *clipboard.write="message">
Copy
</button>
<button type="button" *clipboard.read *response="'clipboardText'">
Read
</button>
Format suffixes are available: .text, .raw,
.json, and .lines. Clipboard access runs only
from explicit user actions.
