Go to Options / Projects / Maemo Device Configurations

Have a non-default value in "Private Key File", "Key" set as authentication type.

Click "Add" to get a new device configurations.

I would like to have the contents of "Private key file" field copied to the new device configuration as well, so that I don't have to re-select the same private key. Typically, you only use one key for all NQS purposes (and it's not necessarily your default ssh key).

Alternatively, it could be a combo box showing a list of previous key selections (but this would be over-engineering?).
