When running jEdit on a Linux desktop with a German keyboard map, the following problem appears:
The jEdit shortcut for "Edit/Source/Go to Matching Bracket" is (by default) C+CLOSE_BRACKET. However, in the German keyboard map, the closing bracket is accessible using the AltGr+9 key combination. Thus, to achieve "C+CLOSE_BRACKET", the user would have to use the Ctrl+AltGr+9 key combination. However, this key combination is not recognized by jEdit, it instead recognizes "C+9" (as evidenced by testing this in the "Utilities/Options/jEdit/Shortcuts" section when trying to use Ctrl+AltGr+9 as shortcut). Thus, the Ctrl+AltGr+9 key combination is interpreted by jEdit as actually Ctrl+9, and both seem to be usable as interchangeably, while a separate Ctrl+AltGr+9 key combination is not accessible. Thus, the "C+CLOSE_BRACKET" key combination is not accessible, and thus, the jEdit shortcut for "Edit/Source/Go to Matching Bracket" is actually not accessible, while it should be accessible.
