I updated RSyntaxTextArea in a project, tried version 2.05 and svn-trunc.
Slashes cannot be used anymore, at least in linux but a coworker had the same problem (using windows afaik)
Problem seems to be within this file:
/org/fife/ui/rsyntaxtextarea/RSyntaxTextAreaDefaultInputMap.java
... around this line (the whole file changed a lot since last stable release)...
