[DUG] XE2 Key mapping

[John Bird]

My XE2 installation has developed the annoyance that if I use CTRL+Up Arrow 
or CTRL+Down Arrow to jump between the declaration and implementation of 
methods, that the IDE will crash with a "Stack overflow - error restart 
XE2".

Any hints how to fix this?

(Code insight seems also to work sometimes and other times not....any 
pointers also where to go to troubleshoot this would be welcome)
