Skip to 5:55 in the video above. There is a small part about kerning.
Basically, type two (or more) Letters you want to kern (for example “AV”) in Type Mode (doubleclick a random glyph to enter edut mode, then press “T” to enter type mode).
Put the cursor in front of the Glyph you want to adjust. The kerning can be changed via keyboard shortcuts (seen in the video) or via the little grey window at the bottom.
In the lower line you should see the fields “K: G: G: K:” - these are used to kern. The left K: is for the kerning between the active Glyph and its left neighbour, and vice versa.
The G: can be used to assign different Kerning Groups for the left and right side. You can group several glyphs with the same characteristics together in one Group to save yourself some repeticious work. (I selected the glyphs in the Overview Screen, and assigned a name via right-click.)
The Kerning Pairs are displayed (but not editable) in the Kerning window. But I don’t understand what that window is all about. To me, it just displays strange gibberish ^^
But please take everything I said with a grain of salt, because currently my font does not get exported with the proper kerning. Most likely I screwed it up somewhere.
