Q re new key command field

Hi I am used to VASSAL 3.4.x, now exposed to 3.5.5 for the first time.

The Perform These Key Commands field used to be just one field, but now there are two, what is that? (not really explained in the Help menu either)…

NVM, I found it in the release notes

Also, when both parts of the KeyCommand field are blank, you will get greyed out ‘hints’ in each field.
