Keyboard Shortcuts
Accelerators
Accelerators are strings that can be used to represent keyboard shortcuts throughout your Electron.
These strings can contain multiple modifiers keys and a single key code joined by the +
character.
Accelerators are case-insensitive.

Cross-platform modifiers
Many modifier accelerators map to different keys between operating systems.
Modifier | macOS | Windows and Linux |
---|---|---|
CommandOrControl | Command (⌘) | Control |
Command | Command (⌘) | N/A |
Control | Control (^) | Control |
Alt | Option (⌥) | Alt |
Option | Option (⌥) | N/A |
Super (Meta ) | Command (⌘) | Windows (⊞) |
- On Linux and Windows, the
Command
modifier does not have any effect. In general, you should use theCommandOrControl
modifier instead, which represents ⌘ Cmd on macOS and Ctrl on Linux and Windows. - Use
Alt
instead ofOption
. The ⌥ Opt key only exists on macOS, whereas theAlt
will map to the appropriate modifier on all platforms.
Examples
Here are some examples of cross-platform Electron accelerators for common editing operations:
- Copy:
CommandOrControl+C
- Paste:
CommandOrControl+V
- Undo:
CommandOrControl+Z
- Redo:
CommandOrControl+Shift+Z
Local shortcuts
Local keyboard shortcuts are triggered only when the application is focused. These shortcuts map to specific menu items within the app's main application menu.
To define a local keyboard shortcut, you need to configure the accelerator
property when creating
a MenuItem. Then, the click
event associated to that menu item will trigger
upon using that accelerator.
const { dialog, Menu, MenuItem } = require('electron/main')
const menu = new Menu()
// The first submenu needs to be the app menu on macOS
if (process.platform === 'darwin') {
const appMenu = new MenuItem({ role: 'appMenu' })
menu.append(appMenu)
}
const submenu = Menu.buildFromTemplate([{
label: 'Open a Dialog',
click: () => dialog.showMessageBox({ message: 'Hello World!' }),
accelerator: 'CommandOrControl+Alt+R'
}])
menu.append(new MenuItem({ label: 'Custom Menu', submenu }))
Menu.setApplicationMenu(menu)
In the above example, a native "Hello World" dialog will open when pressing ⌘ Cmd+⌥ Opt+R on macOS or Ctrl+Alt+R on other platforms.
Accelerators can work even when menu items are hidden. On macOS, this feature can be disabled by
setting acceleratorWorksWhenHidden: false
when building a MenuItem
.
On Windows and Linux, the registerAccelerator
property of the MenuItem
can be set to false
so that the accelerator is visible in the system menu but not enabled.
Global shortcuts
Global keyboard shortcuts work even when your app is out of focus. To configure a global keyboard
shortcut, you can use the globalShortcut.register
function to specify shortcuts.
const { dialog, globalShortcut } = require('electron/main')
globalShortcut.register('CommandOrControl+Alt+R', () => {
dialog.showMessageBox({ message: 'Hello World!' })
})
To later unregister a shortcut, you can use the globalShortcut.unregisterAccelerator
function.
const { globalShortcut } = require('electron/main')
globalShortcut.unregister('CommandOrControl+Alt+R')
On macOS, there's a long-standing bug with globalShortcut
that prevents it from working with
keyboard layouts other than QWERTY (electron/electron#19747).
Shortcuts within a window
In the renderer process
If you want to handle keyboard shortcuts within a BaseWindow, you can
listen for the keyup
and
keydown
DOM Events inside
the renderer process using the addEventListener API.
- main.js
- index.html
- renderer.js
// Modules to control application life and create native browser window
const { app, BrowserWindow } = require('electron/main')
function createWindow () {
// Create the browser window.
const mainWindow = new BrowserWindow({
width: 800,
height: 600
})
// and load the index.html of the app.
mainWindow.loadFile('index.html')
}
// This method will be called when Electron has finished
// initialization and is ready to create browser windows.
// Some APIs can only be used after this event occurs.
app.whenReady().then(() => {
createWindow()
app.on('activate', function () {
// On macOS it's common to re-create a window in the app when the
// dock icon is clicked and there are no other windows open.
if (BrowserWindow.getAllWindows().length === 0) createWindow()
})
})
// Quit when all windows are closed, except on macOS. There, it's common
// for applications and their menu bar to stay active until the user quits
// explicitly with Cmd + Q.
app.on('window-all-closed', function () {
if (process.platform !== 'darwin') app.quit()
})

function handleKeyPress (event) {
// You can put code here to handle the keypress.
document.getElementById('last-keypress').innerText = event.key
console.log(`You pressed ${event.key}`)
}
window.addEventListener('keyup', handleKeyPress, true)
The third parameter true
indicates that the listener will always receive
key presses before other listeners so they can't have stopPropagation()
called on them.
Intercepting events in the main process
The before-input-event
event
is emitted before dispatching keydown
and keyup
events in the renderer process. It can
be used to catch and handle custom shortcuts that are not visible in the menu.
const { app, BrowserWindow } = require('electron/main')
app.whenReady().then(() => {
const win = new BrowserWindow()
win.loadFile('index.html')
win.webContents.on('before-input-event', (event, input) => {
if (input.control && input.key.toLowerCase() === 'i') {
console.log('Pressed Control+I')
event.preventDefault()
}
})
})
