Your ability to view and edit your key ring has been simplified and improved in envelope v1.0. The screen shot below shows the key ring viewer window which allows you to create, edit and delete keys.
The key ring viewer window in envelope v1.0
By double clicking on a key in the key ring viewer window, the key editor window for that key will open. The key editor window for Phil Zimmerman's public key is shown below. Since I do not possess Phil's secret key, I can only change the trust level that I assign to his key. If I open the key editor for my own key, then I can change my pass phrase or add aliases for my key by clicking the corresponding button in the key editor window.
