Here's a quick tip that might make your key management easier. Rather
than copying/pasting/cutting the authorized_keys file, I create a keys
subdirectory where I store the keys I want to use, one key per file.
When a change is made, (deleting or adding a new key) I simply cat * >
../authorized_keys to refresh the file.
