In the Insert menu, you should find "Separated Frame Below", the
default binding for which is Alt+P Return. That will both insert a
separator and start a new frame in one gulp.<br>
<br>
I don't know what you mean about centering equations. I just hit
Ctrl+Shift+M to get a math inset in display mode, then change the
type of equation if necessary. The equations are centered on the
slide, at least to my satisfaction. Perhaps you should post a
minimal working example with an off-center equation to the user
list.<br>
