Fred,

The need to mouse click is certainly a bug, though after some digging it looks 
like it might be a WX one, so I am not sure what, if anything can be done.

I traced through your code below, and interestingly enough, <ctrl> +i is getting 
reported as the Tab character (!?)  I'll see if I can find out why, but in the 
mean time you can try a different key combination. I tried <ctrl> +x for 
instance, and that worked.
