c83f836faf* docs: add references to app.whenReady() in isReady
* refactor: prefer app.whenReady()
In the docs, specs, and lib, replace instances of `app.once('ready')`
(seen occasionally) and `app.on('ready')` (extremely common) with
`app.whenReady()`.
It's better to encourage users to use whenReady():
1. it handles the edge case of registering for 'ready' after it's fired
2. it avoids the minor wart of leaving an active listener alive for
an event that wll never fire again

# Accelerator
|
|
|
|
> Define keyboard shortcuts.
|
|
|
|
Accelerators are Strings that can contain multiple modifiers and a single key code,
|
|
combined by the `+` character, and are used to define keyboard shortcuts
|
|
throughout your application.
|
|
|
|
Examples:
|
|
|
|
* `CommandOrControl+A`
|
|
* `CommandOrControl+Shift+Z`
|
|
|
|
Shortcuts are registered with the [`globalShortcut`](global-shortcut.md) module
|
|
using the [`register`](global-shortcut.md#globalshortcutregisteraccelerator-callback)
|
|
method, i.e.
|
|
|
|
```javascript
|
|
const { app, globalShortcut } = require('electron')
|
|
|
|
app.whenReady().then(() => {
|
|
// Register a 'CommandOrControl+Y' shortcut listener.
|
|
globalShortcut.register('CommandOrControl+Y', () => {
|
|
// Do stuff when Y and either Command/Control is pressed.
|
|
})
|
|
})
|
|
```
|
|
|
|
## Platform notice
|
|
|
|
On Linux and Windows, the `Command` key does not have any effect so
|
|
use `CommandOrControl` which represents `Command` on macOS and `Control` on
|
|
Linux and Windows to define some accelerators.
|
|
|
|
Use `Alt` instead of `Option`. The `Option` key only exists on macOS, whereas
|
|
the `Alt` key is available on all platforms.
|
|
|
|
The `Super` key is mapped to the `Windows` key on Windows and Linux and
|
|
`Cmd` on macOS.
|
|
|
|
