// Package hotkey provides the basic facility to register a system-level
// global hotkey shortcut so that an application can be notified if a user
// triggers the desired hotkey. A hotkey must be a combination of modifiers
// and a single key.
//
// Note platform specific details:
//
// - On macOS, due to the OS restriction (other platforms does not have
// this restriction), hotkey events must be handled on the "main thread".
// Therefore, in order to use this package properly, one must start an
// OS main event loop on the main thread, For self-contained applications,
// using [mainthread] package.
// is possible. It is uncessary or applications based on other GUI frameworks,
// such as fyne, ebiten, or Gio. See the "[examples]" for more examples.
//
// - On Linux (X11), when AutoRepeat is enabled in the X server, the
// Keyup is triggered automatically and continuously as Keydown continues.
//
// - On Linux (X11), some keys may be mapped to multiple Mod keys. To
// correctly register the key combination, one must use the correct
// underlying keycode combination. For example, a regular Ctrl+Alt+S
// might be registered as: Ctrl+Mod2+Mod4+S.
//
// - If this package did not include a desired key, one can always provide
// the keycode to the API. For example, if a key code is 0x15, then the
// corresponding key is `hotkey.Key(0x15)`.
//
// THe following is a minimum example:
//
// package main
//
// import (
// "log"
//
// "golang.design/x/hotkey"
// "golang.design/x/hotkey/mainthread"
// )
//
// func main() { mainthread.Init(fn) } // Not necessary when use in Fyne, Ebiten or Gio.
// func fn() {
// hk := hotkey.New([]hotkey.Modifier{hotkey.ModCtrl, hotkey.ModShift}, hotkey.KeyS)
// err := hk.Register()
// if err != nil {
// log.Fatalf("hotkey: failed to register hotkey: %v", err)
// }
//
// log.Printf("hotkey: %v is registered\n", hk)
// <-hk.Keydown()
// log.Printf("hotkey: %v is down\n", hk)
// <-hk.Keyup()
// log.Printf("hotkey: %v is up\n", hk)
// hk.Unregister()
// log.Printf("hotkey: %v is unregistered\n", hk)
