Like cats, MS Word likes to hide things in secret places.
For example, those styles you know were there but have now gone missing. Where did she put them? Who knows why, such is her charm.
As a small child growing up some people called Word Tips and Tricks a bit of a dog. We was hurt at the time, not being educated and all.
But, like all good dogs, we keep hunting until we find things. Yesterday, for example, after a good run in the back yard, we found where those pesky hidden styles were. Some of the greyhounds over on Klariti made this video. See if it helps.
