Hi Robert, it is possible to set up a keyboard shortcut that will do an open or a save of a fixed file name so that you can trigger that shortcut without using any file dialog.

To do that, set up the file name as a parameter to the Open or SaveAs commands by putting in the filename after a space after the command name.

So for example to open a specific file with a keyboard shortcut, set up the shortcut key with the following:

Open c:\files\myfile.3dm


To save to a specific .obj file with a keyboard shortcut, set up the shortcut key like this:

SaveAs c:\files\myfile.obj



That will do one specific fixed file and not necessarily just the last saved file, but hopefully that will work for you if you're just using a specific file over and over again.
