So, I'm looking into how to do custom keyboard shortcuts for Advanced OVR. I want my [B] button on the Index to press [Ctrl] + [Alt] + [F1], but I don't I know what the syntax is.
I think I found the settings file you have to do it in, it's this one:
>C:\Users\anon\AppData\Roaming\AdvancedSettings-Team\OVR Advanced Settings.ini

And starting line 86 it says:
>[keyboardShortcuts]
>keyboardOne=^>m
>keyboardTwo=^>m
>keyboardThree=^>m

The documentation on the github (https://github.com/OpenVR-Advanced-Settings/OpenVR-AdvancedSettings) and the manual (https://steamcdn-a.akamaihd.net/steam/apps/1009850/manuals/Steam_Guide.pdf?t=1586890366) say it does this:
 >Sends the key sequence defined the the settings file. Defaults to Ctrl+Shift+M (Discord default toggle mute).

So, I assume 
>^>m
means
>[Ctrl]+[Shift]+[M]
in which case
>^
means [Ctrl] and
>>
means [Shift].

But how do I do an [Alt]? I thought into looking how AutoHotkey does it, but apparently they use a different convention, e.g. [Shift] is written as "+" there, though "^" means the same.
So my question is, how do I do an [Alt], or better, how do I do a [Ctrl]+[Alt]+[F1]?
