Thanks. What I am really trying to understand is is it possible for my to validate my private key using Electrum on an offline PC but without creating a new wallet or sweeping it? What I've noticed is that if I enter the private key in that window the Next button becomes ungreyed. However if I enter that private key with a single character deviation the Next button remains greyed out. In essence I have an old priavte key that I would like to test is still valid but without moving the funds from it.
