Trouble Creating IK Chains

I don’t have much experience with IK Chains, so that could be the problem. In the users manual, it says that to make an IK chain you need to select the tip of the chain and press ctrl+I, but when I do that, it only reverses the selection. Any ideas of what I’m doing wrong?
Thanks!

Select the tip of the chain (not the IK target, the one before it) and press “Shift + I”

(Make sure you’re in pose mode)

Great! it worked! Thats a lot Asano. Why does it say ctrl+I in the user manual then? or is that out dated?
