Your insights would be appreciated if you can post how you set it up. Seems things would be easier if we had keyboard support for some things... Maybe down the road as an enhancement.
If you're talking about how I set up the key assignments, then that is available from the options menu on the pc. There's a huge list of things to play with, but it's easy enough to change one, you just select one of the two 'slots' for the action, then use the key/control you want to set it off, which adds it in (there are in-built checks for duplicates).
For voice attack, I use HCS voice packs and they have the settings built in (I actually had to reset a couple of my bindings back to default to accomodate their settings, which was not a problem thankfully).
I'm, obviously, still waiting to see what the PS4 options menu will look like . . . I just hope to be able to find keyboard use being allowed for control bindings as well as the HOTAS.
