Have you tried it?

Tony is correct; the finder.dot add-in template overrides the default
shortcut key assignment and uses Ctrl+Alt+F to launch the macro.

You can assign any other shortcut that pleases you.
- First move the Finder.dot template out of the Startup folder to some other
location (use Windows Explorer while Word is shut down).
- Restart Word. Open the Finder.dot template directly, using the Open
dialog.
- Go to Office button > Word Options > Customize, and click the Customize
button at the bottom of the dialog to get the Customize Keyboard dialog.
- Be sure the Save Changes In dropdown is set to Finder.dot.
- Choose Macros in the Categories column, and then Finder in the Macros
column.
- Select the entry in the Current Keys box and click Remove. Then put the
cursor in the "Press new shortcut key" box, type the shortcut you want, and
click the Add button and then OK.
- Save and close Finder.dot. Move it back into the Startup folder and
restart Word.
