That can certainly be scaled differently.  Right now it's just a slider 
from -30 to +30 and tunes at a rate of n^2 Hz every 10th/second.  I can 
add repeat to the buttons, though I'll have to figure out the best way 
to do that.  I was thinking of adding a right-click function on the 
buttons to have it round to the nearest 1 Khz or whatever.  It's hard to 
hit an exact frequency with the slider alone.

It does.  Try changing the sidetone level or sidetone frequency from the 
keyboard.  You need to have the system focus on the program window for 
it to respond to key-commands, but they should be global within that scope.

Remapping the keyboard can be done, but that's something I'll have to 
build in later--I just figured out how to do global key bindings when I 
was building this last week, but it seems simple enough to make them 
user-defined.  Memories and VFO's are as cheap as memory in the CPU, so 
that's not really a problem.
