Unknown Apple Software (A-K)
This chapter lists selector codes of which the meaning is not documented and are installed by Apple Computer software, and the first character of the selector code is in the A-K range.

I've only seen the value 0, 5 or 6 returned. The GDEF calls the Power

Most are guesses. Well not entirely, I used the ResEdit CODE Editor
to peek into the 32-bit System Enabler, Hardware System update and
other software. Please check if I'am right. You should be able to
find some of the answers in the INIT resource of the Hardware Update
and the names of the PTCH resources in version 1.0 were also useful...

According to Apple its use can cause damage and support problems.

/* all the following bits are not defined prior to Finder 7.5.4 ? */
gestaltFinderDisableTranslucent? = 0}; /* if set, no translucent

See the 'fnd¡' (option-5) selector to change Finder 8 features.
This selector is installed on a PowerBook 5300ce by the
Powerbook 5300/2300/190 Enabler to disable translucent dragging
with System 7.5.2 only. Later systems don't include this enabler
and translucent dragging works fine.

NOTES:
The last byte is an option-x (0xC5).
See the 'fndµ' (option-m) selector to DISABLE Finder 7 features.
See the 'fnd¡' (option-5) selector to change Finder 8 features.
Apperantly the Finder team implemented several features not approved
by the 'high command'. Under normal circumstances these features are
not available, unless the correct bit is set with the response of
this selector. There are probably more bits defined, or already
obsolete because the feature got implemented with later versions of
the Finder. (Anonymous)
Setting bit 1 causes a new menu item to be added to the Finder's File
menu, just below "Find Again". The new item is "Reveal Original" and
it instantly resolves alias files! (Marco Piovanelli)
And it also reveals the application the selected document is opened
with when double-clicked. (Jon Pugh)
Finder 7.5.5 adds, at least, two more bits to this list. When bit 2 is
set, using the Command-Delete moves the current selection to the Trash.
With bit 3 one can turn the zoom rectangles, visible when opening and
closing windows, on and off.
System 7.5.3 and System 7.5 Update 2.0 includes Finder 7.5.5.

#define gestaltInfraredHardwareAttr? 'irhw'
NOTE:
On a PM 7100 with System 7.5.3 universal this selector returns noErr
and a response value of zero. (Jean-Pierre Curcio)
It returns 4 on a PowerBook 5300ce (System 7.5.5 US and KanjiTalk
J1-7.5.3) but it crashes MacsBug. Only by replacing 'eajt' in the
Gestalt dcmd of MacsBug 6.5.3 with 'irhw' ('eajt' is ignored by the
Gestalt dcmd!) the crash can be diverted.
This selector is ignored with MacsBug 6.5.4a4 or later.
