When you need to kern many similar glyphs at once, like A, À , Â  and Á , you can now save much time by linking the kerning values of all accented glyphs to a single one, like the original A. 

So once you have kerned the two pairs AV and VA , all the other pairs like ÀV, ÂV, ÁV and  VÀ, VÂ, VÁ will be automatically created. How cool is that? 😀

Now how about linking only the left sides of your C , G and Q with the kerning values from your O - but only when it's the second letter of a kerning pair, like VO ?

Well, kerning groups can also be used to constrain a single side of glyphs. For instance, you can link all kerning values related to the left side of the glyph Æ  to the pairs ending with an A, like TA or VA , so you don't have to kern TÆ or VÆ .

The kerning table now contains 2 tabs, one for Pairs and one for Groups.

We recommend to start creating your kerning groups before making kerning pairs in order to avoid duplicate work.

In other words, you can tell Fontself that the left or right side of a glyph should get the same kerning value as another character, thus leading to precise adjustments.

If you need to apply a different value for a specific kerning pair that is part of a group, you can unlink the value from the master pair by clicking on the lock icon:

Well, that will highly depend on the design of your typeface, but here are a few tips.

For capitals, the grouping can be pretty straightforward:

Due to kerning issues with lowercase accented characters - like Ta  and Tä - you might have to split a group in two, with the non-accented character like a serving as a first group master, and an accented character like ä  as a second master for the accented lowercase characters.
