What information is tracked under the *Reviews* tab in the *Activity* section of a user's profile?

I assume this section is related in some way to actions which are performed on [**posts listed for review**][2]. But I thought that I had reviewed some posts which were in this list, yet nothing has changed under [***Reviews* in my profile**][3]. 

I clearly do not understand the *Reviews* tab or the information it is meant to provide.

###I think I understand now

If you *suggest* an edit then this is tracked under the *Suggestions* tab in the *Activity* section. If you review a suggested edit and either approve or reject it, then this is (apparently) tracked under the *Reviews* tab.

Since I lack the karma to do any approving or rejecting, there is not going to be any activity under my *Reviews* tab.
