In your Arma3 local folder there should be a PDF, 'arma3_keyboard_layout.pdf', for default bindings. I believe ACE has one too, but you will l have to google that.
Just to add to this for those who don't know how to reach the Arma 3 directory folder,
>Go to your Steam library
>Right click on Arma 3 and choose "Properties..."
>Click on "Local Files" on the left side of the menu
>Click on browse on the right
This will open the game directory file from there you will see the "arma3_keyboard_layout.pdf" It can be printed and even shows you how to make it into a standing thing that you can just set on your desk. But the best way to learn is to just practice and play the game then it will become muscle memory. Fill in when you are able and play the public server or even play through the campaign if you haven't yet, you'll have it all down in no time.
