# Accelerator > Define keyboard shortcuts. Accelerators can contain multiple modifiers and key codes, combined by the `+` character. Examples: * `CommandOrControl+A` * `CommandOrControl+Shift+Z` ## Platform notice On Linux and Windows, the `Command` key does not have any effect so use `CommandOrControl` which represents `Command` on OS X and `Control` on Linux and Windows to define some accelerators. Use `Alt` instead of `Option`. The `Option` key only exists on OS X, 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 OS X. ## Available modifiers * `Command` (or `Cmd` for short) * `Control` (or `Ctrl` for short) * `CommandOrControl` (or `CmdOrCtrl` for short) * `Alt` * `Option` * `AltGr` * `Shift` * `Super` ## Available key codes * `0` to `9` * `A` to `Z` * `F1` to `F24` * Punctuations like `~`, `!`, `@`, `#`, `$`, etc. * `Plus` * `Space` * `Backspace` * `Delete` * `Insert` * `Return` (or `Enter` as alias) * `Up`, `Down`, `Left` and `Right` * `Home` and `End` * `PageUp` and `PageDown` * `Escape` (or `Esc` for short) * `VolumeUp`, `VolumeDown` and `VolumeMute` * `MediaNextTrack`, `MediaPreviousTrack`, `MediaStop` and `MediaPlayPause` * `PrintScreen`
