In pitmenu (F12) left/right arrow keys are used to turn damage-repair on or off.
If pressing the same key multiple times then it "cycles": on,off,on,off,...

So it is not possible to set this option without looking at state of menu.

I think it would be better if does not cycle but instead
left = off
right = on

Why:
-allows to blindly toggle repair
-prevents accidental 'pressing once too much'
-allows binding "turn repair on/off" keybinds to wheel

I didn't get this bit. You can make toggling keybind by some script like this:

and it will be cycled.

BUT, if you make it non-cycling, you can make even better 1-button scripts like this http://en.lfsmanual.net/wiki/Script_Guide#.22F9_.3E_F10_.3E_F11_.3E_F12_.3E_Off.22_Toggle with indication (like adding "/echo repair off" and "/echo repair on" to approporiate script)

So, this one is must have

Yes, I know about the scripting but this does not solve it I think:
You can have one button that toggles it, but you do not know the state of the toggle.
(you press the button and have then turned it from off to on - or maybe from on to off?)

The main advantage of this imo would be being able to turn repair on/off blindly.
Currently you have to first read what the status is, and then set it.
This is a small disattraction and any second counts in pit

I meant binding to two buttons like this:
Button #1: turn repair on
Button #2: turn repair off

Or if you want to use such switch for repair:



It is only a tiny thing.
But anything that requires to take eyes of the road can sometimes be disattraction.
Especially some Aston or Kyoto pitlanes with their chicanes.

Yes, I totally agree that non-cycling way would be more flexible.

EDIT: and there is even way tomake it compatible to the older version. We can have Home and End buttons for it for example, that do not cycle through, while keeping arrows working as it was before.

You can make it non-cycling if you ONLY use scripts.

toggleRepairOn.lfs
/ctrlf 11 /echo Repair already on!
/press F11
/press F12
/press DOWN
/press DOWN
/press LEFT
/ctrlf 12 /run toggleRepairOff
/echo Repair is ^2ON^8!

toggleRepairOff.lfs
/ctrlf 12 /echo Repair already off!
/press F11
/press F12
/press DOWN
/press DOWN
/press LEFT
/ctrlf 11 /run toggleRepairOn
/echo Repair is ^1OFF^8!

Well yes, but if you forgott about it once and change it via F12 it will always toggle wrong way around..
