Summary: PROBLEM IN R: Hard to stop locator() and identify(1)

Initial Comment:
If you run locator() without specifying a number, or identify(1) and can't select the required point for some reason (it happened to me today), you've no way obvious way of getting out of it, and R is blocked. It took me a few minutes to understand that right-click was a solution.

I think Esc should stop these commands, but also that Ctrl+C and the "Interrupt all commands" button should work too. Closing the dialog, moving to another graph, etc. should also stop them, instead of hanging.

(One could also dream of integrating these commands into the dialog, but that's another issue. ;-)

Message:
I should add: there's maybe a bug in RKWard in the sense that it blocks
when trying to close the graph window. This probably prevents the crash on
your machine, but it makes it impossible to stop locator() this way.

Message:
Ah, I could have checked. I'll look for reports and file a new bug if it
isn't known.

(But I don't experience the crash here on Fedora 15 x86-64, so you'll need
to report it directly...)

Message:
Confirmed. However, the same happens when using a regular R console,
outside of RKWard. This probably needs fixing in the X11 device. BTW, when
trying to close the device in this situation, R 2.14.0 (debian sid, i386)
crashes on me. At least we don't trigger the crash in RKWard...

Have you checked the R bug tracker for any matching reports, yet?

Indeed. And it should be fairly easy to implement as a plugin. However, as
long as these commands have such severe issues, it may not be a good idea
to lure users into trying them...
