[DogParkList] Keybindings

[brett]

Hi Don,

Any chance you'd consider enabling emacs keybindings in MLDX? For  
some of the text entry work, it would save a ton of time. My fingers  
type them without thinking about it, so it just slows things down  
when they don't work hihi ;)

Pretty straight forward, unless you're doing something crazy in the  
textboxes...

thanks and 73,
