Disclaimer: I am completely new to this, just got the program a few days ago so please bear with me.
Yes I have read the manual, watched tutorials, googled until I could google no more and I still can't figure it out.
With that said, this should be an easy one for you guys.
I've made my font, set my sidebearings, and now I am refining the kerning. I am NOT using kerning classes, because a) this is a handwritten font and each character is unique, and b) it would take me longer to figure out that process than to just manually kern in the metrics window.
Here is what I did... step by step
Opened the Preview/metrics window
Switched to kerning mode
Typed different combinations of letter pairs together--when I was done kerning each pair I would simply backspace and type in a new pair and re-kern. This would add a new pair to the list on the right so I assumed it was saving them. When I retyped those letters again it remembered my kerning.
But then when I generate the font, the kerning is not saved. When I preview in metrics mode, the kerning is not saved. It is only "saved" when I'm typing in the kerning mode. Example:

When I click kerning assistance it is empty, with no classes (I assumed as much since I didn't make any classes, but I read in the manual that you had to press update [kern] feature to save your kerning... which won't work for me since I have no kerning in that list to be saved)
Please, pretty please, someone explain to me how to save my kerning pairs in five-year-old terms. I just want to finish this font!

Thank you.
