[CQ-Contest] Morse Trainer - filter bandwidh

[Jovica Todorovic]

HI Alex, VE3NEA

Thanks for the great CW contest simulator. I understand that the CW
filter bandwidth can be set from the drop down menu (100-600 Hz). It
would be nice to have assigned hot-key for the common filter
combination like 500 Hz / 250 Hz. It is easier to press something like
Ctrl+F (or Alt+W/N) and toggle between 500 Hz and 250 Hz band pass
without using the mouse. In addition to this you could show the actual
position (ruler scale) of the RIT in relate to "zero beat".

Other than this, this is UFB. Keep up the good work.
