Hi Ralf, yeah it could be possible to set up a shortcut key to import a specific file.

To do that, go to Options > Shortcut keys, and add in a new shortcut.

For the "Key" column put in whatever key you want to trigger it, and for the "Command" column put in Import followed by a space followed by the specific file name, something like this for example:

Import c:\parts\Part1.3dm

Then when you trigger that key, it will directly import that specific file instead of asking you for a file name.

Be careful not to trigger it multiple times in a row or else you'll get stacked up duplicate objects.
