Does anybody know the syntaxes of these features (Proportional Alternate Halfwidths and Proportional Alternate Vertical Metrics)?

FontCreator doesn't yet support GPOS, which is required for these features.

For now, you will have to use VOLT or the OpenType Compiler to add these features to your fonts.

See this tutorial thread on adding OpenType Features with the OpenType Compiler.

FontCreator does support this since a couple of years.

Both Proportional Alternate Widths (palt) and Proportional Alternate Vertical Metrics (vpal) features require a single adjustment lookup.
