Here's a command line kluge that does some of what you want:

pro getdefval,x
; Give a user 3 seconds to supply a value, otherwise use a default
t= 0
print,'Choose x,y, or z: ',format='(A,$)'
while t lt 30 do begin
wait,0.1
t += 1
x = get_kbrd(0)
if byte(x) ne 0b then break
endwhile
print,' '
if byte(x) NE 0b then print,'Using user supplied value of ',x else begin
x = 'z'
print,'Using default value of z'
endelse

return
end
