appkit:click

(appkit:click button)

Performs the button's action as a user's click would -- the way a script drives a window without a human. Answers nil. Part of the appkit package, a Cocoa widget layer written in rontolisp over objc and loaded on first use: macOS (java -jar, the rontolisp binary, or a compiled .class / .jar; never a .wasm), with a display. See the macOS GUI guide.
