Did you read the tutorial on [Adding OpenType Features](https://forum.high-logic.com/t/adding-opentype-features-in-fontcreator/4744/1)?

Before you can add a lookup table for kerning pairs, you must add a kern feature.  
Before you can add a kern feature, you must add a script.

If the OpenType Designer is blank, click on the Code Editor… button to add a default script and some default features based on the glyphs available in your font. You can delete any features that you don’t need afterwards.

Select the default script and click the + button to add a kern feature  
Select the kern feature and click the + button to add a pair adjustment lookup  
Now you can add individual kerning pairs to the lookup table.

Autokern will do all of this for you, creating classes to use for kerning, which is much more efficient than kerning individual pairs; e.g. instead of individual pairs for Ta, Tà, Tá, Tä, etc., just add one pair for @T\_Caps and @a\_lc.
