[NTG-context] Left-justifying the date in the letter module

I am still having a problem with left-justifying the date in letters. The date is towards the left but is aligned several mm to the right of the other text. \usemodule[letter] %% Omit the word "Date", attempt to left-justify date (doesn't align perfectly) \setupletterlayer[reference][alternative=c] \defineletterelement[layer][address][example]{\correspondenceparameter{toname}\par} \setupletterlayer[address][alternative=example] \starttext \startletter[ toname={The Addressee}, opening={Dear Addressee:}, closing={Best regards,}, signature={I.M. Sender}] \input knuth \stopletter \stoptext BTW are the values for the "alternative" key ("example", "e", "c", etc.) documented somewhere? Thank you again. Best, Michael
