This was written right-quick on a subway trip, but consider something al= ong the lines of...

startTime =3D this.inPoint;
transDur =3D 30;
startX =3D 0;
xOffset =3D 1000;

linear(time, startTime, startTime + framesToTime(transDur), startX, star= tX + xOffset)

Where transDur is the duration of the transition, startX is the beginnin= g X value and xOffset is the amount to move X.

Thanks Chris! Both the suggestion and the script are very close to what I w= ant and solve a bunch of problems (like having the back page color or page = turn width changes ripple through the project). My only issue now is that b= y key-framing the page turn, the instanced effect creates the transition on= a new layer where it is in time on the original layer. I need these layers= staggered in time so that's not going to work. Could anyone figure out= an expression to change the fold position on the x-axis as a function of t= he layer's in point? I know there's an auto-fade opacity by layer i= n/out expression, maybe telling it to take 30 frames from layer in to trave= l 1000 units in X would work. Then I could instance that effect with the ex= pression and maybe it would change the rest of them at the same time...?

If these slaves will be in other compositions, then when you= create your first slave, put it in another composition, pointing back to t= he master layer in the master comp. You can wire expressions across comps b= y having both Timeline panels open at the same time (just drag one timeline= 's tab above the others, and a new frame will be created in the UI), th= en follow the above.

What might also be of use is someone has created a scri= pt that creates an "instance" of an effect where every parameter = of an effect applied to a slave will be attached to every corresponding par= ameter of a master - saves a lot of pick-whipping if you need to set up a l= ot of parameters, instead of just a few expression controls. Let me see wha= t that thing was called=85here it is:=A0http://aescripts.com/ft-effect-instance= /

good luck -
Chris

P.= S. Our books, if you have them, tend to show examples of having one master = layer control multiple slave layers using expressions.
