@shardik: haven't seen this before, but just checked again...
Already done (after Beta 4) is the following in german Editor.catalog:
UpperCase = Auswahl in Großbuchstaben
LowerCase = Auswahl in Kleinbuchstaben
InvertCase = Auswahl umkehren
SelectWord = Gesamtes Wort am Cursor auswählen
UseTabIndentForSplittedLines = Tab-Einrückung für mehrzeiligen Quellcode verwenden
AutoWrap = Automatischer Umbruch am Dateiende
Mesa already did the Catalog updates in English + French for Beta 4.
So now the other languages are left...
