## Local Shortcuts without a Menu
If you want to configure a local keyboard shortcut to trigger an action that
_does not_ have a corresponding menu item, you can use the
[electron-localshortcut] npm module.
## Shortcuts within a BrowserWindow
If you want to handle keyboard shortcuts for a [BrowserWindow], you can use the `keyup` and `keydown` event listeners on the window object inside the renderer process.
```js
@ -57,9 +56,39 @@ window.addEventListener('keyup', doSomething, true)
Note the third parameter `true` which means the listener will always receive key presses before other listeners so they can't have `stopPropagation()` called on them.
If you don't want to do manual shortcut parsing there are libraries that do advanced key detection such as [mousetrap].
```js
Mousetrap.bind('4', function () { console.log('4')})
Mousetrap.bind('?', function () { console.log('show shortcuts!')})
Mousetrap.bind('esc', function () { console.log('escape')}, 'keyup')
// combinations
Mousetrap.bind('command+shift+k', function () { console.log('command shift k')})
// map multiple combinations to the same callback
Mousetrap.bind(['command+k', 'ctrl+k'], function () {
console.log('command k or control k')
// return false to prevent default browser behavior
// and stop event from bubbling
return false
})
// gmail style sequences
Mousetrap.bind('g i', function () { console.log('go to inbox')})
Mousetrap.bind('* a', function () { console.log('select all')})
// konami code!
Mousetrap.bind('up up down down left right left right b a enter', function () {
console.log('konami code')
})
