I am currently playing on the keyboard. im trying to link combos very simple combo like i would do cr.lp, cr.lp, cr.mk with ken but when i plink cr.lk and cr.mk, crouch light kick would come out instead of cr mk. is there a special way to plink on the keyboard or am i just doing it wrong?

this is on the pc version

You’re probably trying to do the link too early. If you’re still in recovery from the crouching lp when you hit the crouching mk, the mk won’t come out whether you’re plinking or not.

you are doing it wrong. as mentioned you are pressing it too early, leading to a cr.lk chaincancel.
You are not linking.
But hey, you discovered one principle for option selects ;), congratz

a mechanical keyboard may help. buttons are more pressure sensitive
