I can not figure out how to flip my text?

I solved this problem really easily (and after a lot of wasted time). The simple, elegant solution is to use the Warp Text feature and NOT the Text to Path feature! (Using PC here) just right click your text layer, choose Warp Text, and adjust from the options on that window, which are pretty self-explanatory. In order to do the bottom half of your cirlce text, you'll probably want to use the 'arc lower' setting.  Good luck!

1. In the SHAPES toolbar, select the ELIPSE tool (not the marquee tool)

2. Make it the size you want and then type your text around the elipse

3. Highlight your TEXT and then ? Go to > EDIT > TRANSFORM** > FLIP HORIZONTALLY
4. Re-Adjust to suit your requirements

5. I use a WHITE BG color for the elipse and then select DARKEN in the LAYERS panel to make this invisible.

** Strangely sometimes TRANSFORM PATH comes up instead of TRANSFORM so pls note this.

Hope this helps someone.
I just did this logo up for a client Tikun Trace Minerals www.tikun.com so I am fairly sure that it works.

I'm a total novice - an infant really.  I know the shift key, but what is baseline shift mean?

Thx!
