Hmm. You are in the node whose node.lua contains the onkeydown handler 
(press "N" to have Pipmak display the number of the current node), and 
you did reload (or leave and re-enter) the node after saving the 
changes to node.lua?
Is the keydown handler function called at all when you press a key? You 
can check by inserting a print statement, like so:

onkeydown (
   function(key)
     pipmak.print("Bingo!")
     if key == string.byte(" ") then
       ...

The whole node.lua file, although it looks like a data file, is 
actually a Lua script that is executed when the node is loaded. All the 
configuration keywords like "cubic", "hotspotmap", "onkeydown" are 
actually Lua functions that manipulate the internal state of the 
engine. Is the "onkeydown" function that installs the keydown handler 
called on reloading the node, as it should? To check, use print 
statements before and after it:

pipmak.print("Before!")
onkeydown (
   ...
)
pipmak.print("After!")

If these tests don't lead us to a solution, there might be something 
wrong in Pipmak itself, and I'd have to find and fix that.
