# chart.panKey

Allows setting a key to switch between zooming and panning. Can be one of `alt`, `ctrl`, `meta` (the command key on Mac and Windows key on Windows) or `shift`. The keys are mapped directly to the key properties of the click event argument (`event.altKey`, `event.ctrlKey`, `event.metaKey` and `event.shiftKey`).
