.QW "YourApp Help"
performs the default Cocoa action of showing the Help Book configured in the
application's Info.plist (or displaying an alert if no Help Book is
set).
.TP
\fB::tk::mac::PerformService\fR
.
Executes a Tcl procedure called from the macOS 
.QW Services 
menu in the Application menu item. The
.QW Services
menu item allows for inter-application communication; data from one
application, such as selected text, can be sent to another application
for processing, for example to Safari as a search item for Google, or
to TextEdit to be appended to a file. An example of the proc is below,
and should be rewritten in an application script for customization: 
.RS
.PP
.CS
proc ::tk::mac::PerformService {} {
    set data [clipboard get]
    $w insert end $data
}
.CE
.RE
Note that the mechanism for retrieving the data is from the clipboard;
there is no other supported way to obtain the data.  If the Services 
process is not desired, the NSServices keys can be deleted from
the application's Info.plist file. The underlying code supporting this
command also allows the text, entry and ttk::entry widgets to access
services from other applications via the Services menu. The NSPortName
key in Wish's Info.plist file is currently set as
.QW "Wish"
; if a developer changes the name of the Wish executable to something
................................................................................
If defined, launches a URL within Tk. This would be used if a Tk
application wants to handle a URL itself, such as displaying data from
an RSS feed, rather than launching a default application to handle the
URL, although it can defined as such. Wish includes a stub URL scheme
of
.QW foo://
in the CFBundleURLSchemes key of its Info.plist file; this should be customized for the specific URL
scheme the developer wants to support. 
.TP
\fB::tk::mac::GetAppPath\fR
.
Returns the current applications's file path.

time in the past.  In that case the Tk build directory will contain
its own copy of Wish.app that will be visible to LaunchServices.  It
may be necessary when testing your app to take some steps to ensure
that LaunchServices is launching the correct Wish.app.  Instructions
for doing this are provided below.

The command line tool which manages the LaunchServices database has
an amazingly unwieldy path name.  So, first, run this command: 

alias lsregister='/System/Library/Frameworks/CoreServices.framework/Versions/A/Frameworks/LaunchServices.framework/Versions/A/Support/lsregister'

Then you can reset the LaunchServices database like this:

$ lsregister -kill
$ lsregister -seed
