This is a wish-list item, but hopefully a fairly easy one to implement and I think quite an obvious thing to want to do! (I've been using 3.4 and 3.7)
I often open large numbers of files simultaneously (using things like "joe `rgrep -l 'something' .`") and sometimes I want to quit joe after editing the one or two files that turn out to be actually relevant, but I have to ctrl-C all the files separately (which can take a while if I've opened a few hundred files!) I'd like a keyboard shortcut equivalent to ctrl-c on every file, ideally still confirming quit-without-save, so I can close all saved / unedited files in one keypress and then worry about any edited / unsaved files without the noise of many other files open.
If there's an option to do this, then consider this a bug report against the documentation, instead ;-)
Thanks in advance to anyone who implements this or points me to the right part of the docs!
Cheers & God bless
