Hi chu224,
Welcome to Microsoft Answers Community Site.
There are no sensitivity settings for keyboard like pointing devices. If you are facing this issue while playing some games then I would suggest you to check for the game setting to reduce the sensitivity of the directional arrow keys and if the issue persists I would suggest you to get in touch with the game manufacturer for additional support.
Hope this information is helpful.
Thanks and Regards,
Vijay KKS
