L1 key function.

You all know we can cycle through hot bars with the R1 key, however it only cycles in ONE DIRECTION (1-2-3-4-5-6-7-8-1-2-3 etc), and it is sometime very inconvenient. Suppose I am at Hot Bar 3 and wanna switch to Hot Bar 2, instead of pressing one button I have to press 7 buttons. I know I can change to a desire Hot Bar immediately by R1 + a button, but in a chaotic fight my brain WILL be messed up, and thus making it even harder than pressing R1 7 time.
I need a change to the L1 key. I would rather not have the auto-run button, and have the L1 key as a key to cycle the hot bar IN AN OPPOSITE DIRECTION as the R1 key (8-7-6-5-4-3-2-1-8-7-6 etc).

Any thought about this?

I agree with this wholeheartedly. Rarely do I ever use auto run because the terrain is so beautifully unstable and not just a flat land so I drive with my joysticks. Often in a battle I switch bars and accidentally skip the desired bar so instead of being able to press L1 to go backs bar, I have to skip over multiple bars to get back where I need to be. I find myself pressing L1 anyways because my brain sees that as logical, yet it doesn't work.

This needs to be added to the c

Are you aware of the Enable Customization while in combat option in the Character Customization -> Hotbar -> Cross tab menu? You can limit the rotation of the R1 button to only cycle a select set of cross bars. I limit it to two and find other ways to shrink the bar usage so that I only have need of those two (with bar change and copy macros depending on usage).
