You can use the default touch menu bar or touch strip to cut, copy, and paste cells. You can also customize the touch bar to provide additional options.

Tap a selected range to display the touch menu bar. The following image displays a default touch menu bar.

You can use the TouchToolbarOpening event to display a customized touch bar. You can also add menu items to the touch bar.

Refer to Using Touch Support with Drag and Fill for information about creating a drag fill option in the touch menu.
