Apple IIe Card - Manual (Page 89)

If you want the Option Panel to open as soon as the IIe Startup program
launches, hold down the Option key just after you double-click the
IIe Startup icon. Keep the Option key held down until the Option Panel
opens.
The IIe Startup program creates and maintains a file called the IIe Prefs
file, which records all the choices you make in the Option Panel. Double-
clicking the IIe Prefs icon causes the computer to switch to the Apple IIe
environment, just as double-clicking the IIe Startup icon does.
When you double-click a preferences file, it reads the preferences from
that file, which is useful if you have more than one preferences file, as
explained in the next section.
