The button is actually named "Edit" in English already too, because "Load" cased confusion to many users.
Hi,
since there is no email address given for the translators, I'll try to get contact here ;-)
I was unsuccessfully searching for the "Load" button in WinSCP to temporarily choose a different encryption algorithm and wondering that there isn't one... When I searched for this button in the forums, I found that there should be one.
Again searching I found out that the "Edit" ("Bearbeiten") button is the original "Load" button. I think that it would be better to get them the original meaning "Load" ("Laden") since the "Save" button is already on the bottom :-) ...
