Sometimes after hitting an iterrupt on the Windows version of Mathematica, I get the following text printed in the notebook cell
Your options are: abort (or a) to abort current calculation continue (or c) to continue exit (or quit) to exit Mathematica inspect (or i) to enter an interactive dialog show (or s) to show current operation (and then continue) trace (or t) to show all operations
How can I actually do any of these things. The keyboard doesn't respond to things like "a" for "c". Normally, things are so fouled up at this point I end up disconnecting from the kernal, but I'm still curious. - Gerry F.
