Actually I quite don't understand what you mean here. Would you be so kind to give a screen shot or 
so?

In certain aspects of RKWard yes on other parts saddly no. Editing R-code depends largely on 
functions provided by KDEs Kate editor. This is from the help:

"Most shortcuts are not yet configurable (this will be added in a future release), but you can 
configure most shortcuts of the script editor. To do so, open a script editor window, then 
choose 'Settings->Configure editor->Short cuts' from the menu."
A lot of these things is hard coded in the source code, therefore there is no easy way for 
non-developers to fix according to their needs. Sorry for that. Anyway you can find additional 
information in the RKWard help. Sorry but RKWard is still work in progress.

Could please try to give the error output?

Hope I understand you correctly. The Output tab is used in case you have done any operation from the 
menus but not if you use the script editor or the console.

Just in case Rward turns out not to be what you need, did you consider to run Tinn-R via Wine 
(www.winehq.org/)? I tested it and at least it installed and did operations like opening files and 
so on. Of course you would also need to install R under Wine. Wine should come as a standard 
package with openSUSE. I'm not sure about the version here in Debain/Sid it is 1.0.1.


Kind Regards
