Single Click runs the first block on a normal press. Double Click (two taps within 300 ms) runs the second block when its Transform is not None — Disabled.

Selected Text sends ⌘C first; Whole Field sends ⌘A ⌘C; Clipboard uses the current pasteboard.

The chosen transform is applied via RoboCore's transform engine — the same engine that powers Textulon and the {rot13}, {json beautify}, … commands in the Keyboard Shortcut action. Only “Open in Textulon” requires Textulon to be installed; the other outputs run entirely inside robo.

Title overrides the label drawn on the key. When blank, the transform name is shown. With double-click enabled, the primary title moves to the top of the key and the double-click title appears at the bottom.
