[Elecraft] K3 Contest Operation Question

[John Watkins]

When I run QRP in major contests like this weekend I search and pounce and work my way up the band bottom to top.  I run with the filter on 2.7.

Using N3FJP logger and winkeyer I was wondering is there a way I can have a keyboard shortcut to switch the K3 from the 2.7 to the 400 filter so I don't have to double tap the xfil button.

Looking for ideas.
