Where can I see my total spell crit chance?

I have put points into crit spell chance on my passive tree but nowhere does it show my the total crit chance, including all of my crit chance from my gear.

When I put a increased critical chance support gem on a spell I can hover over it to see the crit chance.

Is there somewhere to see all the crit chance combined for my character?

It will be on the character stats page which I believe is opened by default with C.

You cannot see the total of your individual modifiers from passives/gear/etc., only the final result as seen on this page. After modifiers my critical strike chance seen here is 14.4%.

If you want you can calculate what your total increased crit chance is. For example:

Base crit chance for Ethereal Knives is 6% but my total crit chance is 14.4%.

14.4 - 6 = 8.4. So I know the total effect is an extra 8.4% crit chance

8.4/6 = 1.4 or 140% increased critical strike chance from passives and gear.
