Alternative syntax: :::wa-copy-button params?ncontentn:

Params: space-separated tokens, any order (rightmost-wins for conflicts) Placement: top, right, bottom, left Tooltip mode: tooltip:full|copy|none (when the built-in tooltip appears) Duration: numeric value (feedback-duration in milliseconds) Flags: disabled Labels: copy-label=“text”, success-label=“text”, error-label=“text” From: from=“element-id” (copy from another element)

Usage: <<< This text will be copied to clipboard <<<

<<<disabled top 2000 Disabled copy button with top tooltip and 2s feedback <<<
