[9fans] Does sam accepts interrupt signal
Hi,
The UNIX standard editor ed, which also exists in Plan 9, accepts the
interrupt signal. When it listens an interrupt signal, ed will print
a `?' and returns to its command level. Frankly, it is a very
convenient feature since the user could not loose himself, especially
for a line editor. But it seems that sam does not handle the
interrupt signal.
I have encountered such a case several times: after operating for a
long time when both mouse language and command language are used
together, sam appears to forget the state (in fact it's I that forget
it) and treat my input as plain text. In this case, no matter putting
a single dot or completing with a `/' could not save me. As a result,
I usually have to look backward in command window to see what exactly
the last command is. Well, I know it may be my fault encountering
such problems. But I think it could be simply solved if sam's
operations could be asynchronously interrupted.
So, is there a feature like this in sam, which I ignored? Or, is
there any other better method to solve similar problems?
Thanks :-)

Re: [9fans] Does sam accepts interrupt signal
it has been some time since i last used sam interactively,
but your description
sam appears to forget the state (in fact it's I that forget
it) and treat my input as plain text. In this case, no matter putting
a single dot or completing with a `/' could not save me. As a result,
sounds as though you've ended up typing behind the point where sam
is actually reading input (ie, in the transcript).
try snarfing and sending a newline (or perhaps a .) to resynchronise.

OK, I see. It's helpful. Thank you~
