Go to atelier/woocommerce/cart/cart.php and find this line (111):
echo apply_filters( 'woocommerce_cart_item_remove_link', sprintf( '<a href="%s" class="remove" title="%s">×</a>', esc_url( WC()->cart->get_remove_url( $cart_item_key ) ), __( 'Remove this item', 'swiftframework' ) ), $cart_item_key );
Change to:
echo apply_filters( 'woocommerce_cart_item_remove_link', sprintf( '<a href="%s" class="remove" title="%s">Update</a>', esc_url( WC()->cart->get_remove_url( $cart_item_key ) ), __( 'Remove this item', 'swiftframework' ) ), $cart_item_key );
Not sure why you would want it to say update though? ‘Remove’ makes more sense
