[WriteLog] Sending a "SPOT" command to a K3

[K2MK]

The SPOT button on my K3 really got a workout while working S&P in the DX 
contest this past weekend. (The SPOT button is used to zero beat the 
received station). I wonder if there is an easy way to send a SPOT command 
to the K3 from the computer keyboard. I was thinking that the wheel button 
might be nice or perhaps F12. (The K3 macro number for this function is 
SWT42).
