moving a caption text box

Hi - I didn't seem to find the answer in an existing post (sorry if i missed one), but I am creating a 'current slide number' caption text as a global layer.  I want it to be 'small' and in the lower right corner.  when i add the caption text, it places the 'box' in the middle of the screen - i can't seem to move it unless i ENLARGE the box.  but then i can't get it to the size i want where the 'current page number' is just a small number in the lower right corner.  

Any suggestions on what I am doing wrong, or how to go about getting this accomplished?  I am a new user, and believe i may have also seen that once i get this done, i may be able to create a 'template' so it will always be where i want it, and i can reuse that template for each slide show.

Thanks!!
