no, unfortunately, there are no hidden features like this. This area simply 
hasn't received too much love so far. We do plan to turn this into a "real" 
debugger, eventually, including syntax highlighting, inspection of the call 
stack, local objects, etc. But don't hold your breath, currently some other 
issues have higher priority.

No, there is not. The R console in RKWard is just an emulation, and that 
feature would need to be programmed into it. Besides, this is not quite 
trivial, conceptually: In a GUI like RKWard, the console does not play the 
central role that it has in a standalone R terminal. Not all commands get 
entered through the console, but they may also come from plugins, the 
data.frame editor, help search, etc. This could create the situation, that R 
is waiting for user input on the R console, but the user just isn't aware of 
that, and all other commands will just wait forever. Thus we need to make sure 
that requests for user input from the backend are always highly visible.

So, while I can see your point, I am not sure this is a good way to handle 
interactive user input situations.

Regards
Thomas
