As you can see, there is a weird space when I type in my indesign CS6. I have it set at 11pt font yet the cursor is clearly much bigger than the text it is writing. How do I remove that large space? Thanks a lot!
I suppose that you have a single sign in this line with different size, probably the return sign.
Go to the paragraph style you are using and click by holding the alt key on it. It will delete all overrides to your paragraph style.
