Intercept clipboard copy, cut, and paste using onBeforeCopyToClipboard and onBeforePasteFromClipboard.

This example shows how to filter or cancel clipboard operations. The hooks run for both keyboard shortcuts and menu actions.

  • onBeforeCopyToClipboard — Receives serialized TLContent plus operation ('copy' | 'cut') and source ('native' | 'menu'). Return a modified TLContent to change what is written, or false to cancel the write (for cut, the selection is not removed).

  • onBeforePasteFromClipboard — Runs when pasted content is about to be applied. Receives source ('native-event' | 'clipboard-read'). Return false to cancel, or a modified TLExternalContent to transform. This hook applies to clipboard paste only, not file drops or other putExternalContent calls.
