This ability doubles the threat range of a weapon. Only piercing or slashing melee weapons can be keen. If you roll this special ability randomly for an inappropriate weapon, reroll. This benefit doesn’t stack with any other effects that expand the threat range of a weapon (such as the keen edge spell or the Improved Critical feat).

Specifically... On a slashing or piercing weapon it reduces the number needed on the D20 to trigger a critical threat.
A critical threat is the chance to land a critical hit, to do so you 'confirm' the threat with another attack roll that hits.

example:
Longsword = 19-20 (2/20 on d20 roll) threat range, damage x2 if threat is confirmed
Keen longsword = 17-20 (4/20 on d20 roll) threat range, damage x2 if threat confirmed

How do we know by how much the threat range is reduced? It doesn't say "keen #". Or is the updated crit threat range the actual crit threat range?

Right click on the weapon. It shows the description there. Normally affixes seem to be purple context words that you can just hover the mouse over to get the description, but not all. Some like Holy/Unholy/Keen you actually have to click the weapon itself.

Means the weapon is extremely sharp, and has a better chance of landing a critical hit than normal.

It doubles it. 20 becomes 19-20 (1 to 2); 19-20 becomes 17-20 (2 to 4); 18-20 becomes 15-20 (3 to 6).

Amazing. Thanks for the great response!
