I am not sure I am understanding on what you mean by 'all your AA hotkeys installed', and whether or not they are being used.
If you are using automation (RGMercs, CWTN) then in general use of AA, skills and spells is handled by the automation. A hotkey is not required. As to whether the automation of choice is using all of them - that is up to the person writing the script or INI file.
If you are actually asking about AA's and whether you have created a hotkey for all of them so that you are able to use them all - I suggest that may not be the way to go about it. In general, you probably don't want individual AA's on hot keys. Instead, you will want a hotkey to trigger a social that does something like trigger your burn abilities. Or defensive hotkeys that trigger specific skills. Skills have different timers and cooldowns, and you will want to make sure you have a hotkey created for basic grouping, burns, and oh shit moments. You will also probably want things on a mash hotkey.
As mentioned, having them on hotkeys does show you which are available and which are on cooldown, which is useful. But I wouldn't be triggering them individually per hotkey personally.
