Hi LLoveBlendingSpinach ,
CTRL+R gives a double Operation, first you place the Loop Cut (and scroll up or down to change the number of Cuts) and then confirm that with a Left Click, and then you can Slide the Cut(s), until you Left Click again, to confirm. It is during this Slide Operation (between the first and second confirm) that you can use E for Even. When you have Left Clicked twice, the Cut(s) is (are) fixed and E will do an Extrude.
