[TxMt] Setting font weight in .tm_properties

[Jon Clayden]

Dear all,

I'd be slightly surprised if I were the first to raise this, but I
don't see any mention of it recently on the list.

Is it possible to set the weight of a font, as well as the face and
the size, from .tm_properties? I'm using Source Code Pro, and I prefer
the Medium weight to the Regular on my current screen. Some of the
theme files seem to use a "fontStyle" key, but setting

  fontStyle = "Medium"

doesn't seem to help.

Thanks in advance.

Jon
