Everytime I hit Ctrl+F to open big-find (or any of several other dialogs) the status bar shows
"Key not defined".
#1: It shouldn't do that
#2: What key? --- reminds me of the stupid "File not found" dialogs that don't say *which* file was not found.
Change line 1059 of stdcmd.e to
message(nls("Key not defined:" event2name(last_event())));
Turns out it is complaining because "ON-SCROLL-LOCK"
This happens just because scroll-lock happens to be on.
