Using the balloon and the gloves with the helium tank

To quickly use the balloon and the gloves with the tank, make sure they're together in the inventory. Then, after using the first of these items with the helium tank and skipping the cutscene, keep the cursor on the helium tank and open the inventory, press the right arrow key and Enter to select a glove, close the inventory, click on the helium tank, and press Backspace to skip the cutscene. Repeat to use the third item.
