Place - script

Just associate shortcut to your script: 

//obviously need all teh preliminary checks but basically…

myContainer.place(File(filePath));

If you really need file to be placed for every single file you work with, use a startup script and an open event listener so it does it automatically (you can of course have a checking routine).

Hi,

You should be able to make use of the Sample that is shipped with InDesign -> PlaceMultiPagePdf.js (Windows->Utilities->Scripts, to open the panel)

This shows how to place a PDF file, and then in the keyboard shortcuts menu item ( Edit->Keyboard shortcuts) you can select any script and assign it a shortcut.

Hope this helps

With no documents open 

File>New Library

Import your PDF/AI file into the library

You can dock the Library with the rest of your panels (save your workspace if you like)

Then in Edit>Keyboard Shortcuts

Go to Prodcut Area:
Panel Menus

Navigate to:

Library: Place Item(s)

And then set your keyboard shortcut.

With one item in the library it will work.

If you have more than one item - it will place the item that is selected
