That doesn't seem to update real time either :( If I select 
Console and change logs, it updates in both windows (Console 
and my tail in Terminal) at the same time.

Haven't tried this, will do if it turns out to be useful for 
future debugging.

I can confirm that arrow keys trigger this on my system too. 
I pretty much always use arrow keys when I backspace, to get 
to the bit I want to delete, hence the confusion.  I just 
checked with vi (which has alternative "arrow" key bindings) 
and it only triggers a pair of those bad keycode lines when 
I use one of the actual arrow keys...the alternative 
bindings are silent.
