I hear a lot from folks on how they have their travel skills arranged and I’ve tried most of them but the easiest for me is to simply use the skill panel.

When you first log in to a character, tap your K to bring up your skill panel.
In the top right corner, click the minimize symbol (=) to close all the categories.

On the left, click the open symbol (+) to open Travel Skills.

On the right, use the slide bar to move up and down the list.

The skills are listed in the order in which they were earned or bought.
There is a search box at the top to help you find what you need.
