For the "Actions" part of the view I propose the following changes in wording:
Buttontext /Tooltip
1) "Generate New Keys" -> Generate New OpenPGP Keys
Tooltip: "Create a new primary key and generate subkeys on the card." -> Create a new primary key with two subkeys on the card.
(If no 6 has OpenPGP, we should use it here, too. Or leave it off in both cases.)
2) "Change PIN"
"Change the PIN required for using the keys on the smartcard." -> Change the PIN required for using the keys on the smart card
3) "Unblock Card"
"Unblock the smartcard and set a new PIN." -> Unblock the smart card with the PUK and set a new PIN.
4) "Change Admin PIN"
"Change the PIN required for administrative operations."
5) "Change Reset Code" -> Change PUK
"Change the PIN required to unblock the smartcard and set a new PIN." -> Set or change the PUK required to unblock the smart card and set a new PIN.
6) "Create OpenPGP Key" -> Create OpenPGP certificate
"Create an OpenPGP key for the keys stored on the card." -> Create an OpenPGP certificate for the keys stored on the card.
Maybe add to the tooltip: "Should only be done if the certificate was lost and you only have the private key left."
Additionally I propose a rearrangement of the buttons.
How about 2 lines for the Action buttons?
Put only 2) and 3) (which are the most common user actions) on the fist line and all the others (which are "admin" options on the second line?
In the order 4), 5), 1), 6) ?
