@subsection Frame Variables
@table @code
@vindex ns-use-proxy-icon
@item ns-use-proxy-icon
This variable specifies whether to display the proxy icon in the
titlebar.
@vindex ns-confirm-quit
@item ns-confirm-quit
This variable specifies whether to display a graphical confirmation
dialogue on quitting.
@vindex ns-auto-hide-menu-bar
@item ns-auto-hide-menu-bar
This variable specifies whether the macOS menu bar is hidden when an
Emacs frame is selected. If non-nil the menu bar is not shown unless
the mouse pointer is moved near to the top of the screen.
@vindex ns-use-native-fullscreen
@item ns-use-native-fullscreen
This variable controls whether to use native, or non-native
fullscreen. Native fullscreen is only available on macOS 10.7 and
above.
@end table
@subsection macOS Trackpad/Mousewheel Variables
These variables only apply to macOS 10.7 (Lion) and above.
@table @code
@vindex ns-use-mwheel-acceleration
@item ns-use-mwheel-acceleration
This variable controls whether Emacs ignores the system mousewheel
acceleration. When nil each `click' of the mousewheel will correspond
exactly with one mousewheel event. When non-nil, the default, each
`click' may correspond with more than one mousewheel event, depending
on the user's input.
@vindex ns-use-mwheel-momentum
@item ns-use-mwheel-momentum
This variable controls whether Emacs ignores the system `momentum'
when scrolling using a trackpad. When non-nil, the default, scrolling
rapidly may result in the buffer continuing to scroll for a short
while after the user has lifted their fingers off the trackpad.
@vindex ns-mwheel-line-height
@item ns-mwheel-line-height
This variable controls the sensitivity of scrolling with the trackpad.
Apple trackpads scroll by pixels, not lines, so Emacs converts the
system's pixel values into lines. When set to a number, this variable
sets the number of pixels Emacs will consider as one line. When nil
or a non-number the default line height is used.
Setting a lower number makes the trackpad more sensitive, and a higher
number makes the trackpad less sensitive.

@cindex Core Text, on macOS
@cindex font backend, on macOS
In macOS, Emacs uses a Core Text based font backend

The behavior of the macOS "Option", "Command", "Control" and
