How would I programmatically open a maple worksheet?

I thought this would work but it brought up a -1

ssystem("c:\\Users\laptop22\Documents\Start2Test.mw")

From the help page it says

To create a custom start page with a similar layout as the default start page, create a table in the worksheet, add a shortcut component to each table cell and modify each shortcut component appropriately.

I'm unable to find how to insert a shortcut component.  Can someone help?

I just happened to be searching older posts and could not find this one I created

It must have be zapped by a spamming filter or something. 

**edit added**  heres another I can't seem to find

Any way to type in dy/dx differentiation without having to use the graphic pallete?

I can do a couple of ways ..

y'

diff(y,x)

but dy/dx direct typing eludes maple, I thought there was a way at one time
