i was surprised: with other keys,  Esc  suppresses the following key:
eg  Esc + a  does no more than rewrite the status line,
whereas  a  asks if/how to add to the bookmark file.
the sequences which work use the  12  letters  l  to  y , omitting  n o .

yes:  Esc  stops a download, whereafter any character resumes;
of course, only during an actual download,
not when the odometer is flipping over after the fact.

i'll just take your word for that ...
