I want to put them in numerical order, but I don't know how. Is it possible?
Press the second button on the bottom of the touch screen with the "arrow circle". This will give you the options of sorting "By Number" and "By Name". By Number will sort your TMs in numerical order. These optins exists for all item types.
Yes, it's very easy. On the toolbar on the bottom screen, one of the buttons will allow you to sort the items. One of the options is to sort them by number.
