An option for output width (equivalent to
	option (width=...)
is available in Settings->Configure RKWard->R-Backend. You're probably right 
that it would make sense to move this and a few others options to the console 
page of the settings.

Yes. The easiest way (not available with all, but with most window managers) 
is to bring up the context menu, then click the right mouse button over "copy 
cleaned"->Configure Shortcut.

You can also use Settings->Configure Shortcuts. The catch is that the console 
needs to have focus when you do so, as only the shortcuts of the active window 
can be configured.

Occasionally there are issues with disappearing shortcuts, and be warned: In 
0.5.3 there were even crashes when configuring shortcuts under some 
circumstances (fixed in our SVN version).

You mean the on-screen plot windows? Simply fire up a new one using
   x11()
on the console. Use
   dev.set()
to activate a specific one (or use Device->Make active) before sending plot 
commands.

This is really not user-friendly, ATM. Use the "Pending Jobs" tool window. 
Select the commands to cancel (usually the topmost one) and press "Cancel 
selected commands". Improving this is definitely on my TODO list...

For commands that you have entered in the console, Ctrl+C will work, too.
