## Keyboard Navigation
* When you hit the <kbd>⬆</kbd> or <kbd>⬇</kbd> key, the input value will be increased or decreased by `step`
* With the <kbd>Shift</kbd> key (<kbd>Shift+⬆</kbd>, <kbd>Shift+⬇</kbd>), the input value will be changed by `10 * step`
* With the <kbd>Ctrl</kbd> or <kbd>⌘</kbd> key (<kbd>Ctrl+⬆</kbd> or <kbd>⌘+⬆</kbd> or <kbd>Ctrl+⬇</kbd> or <kbd>⌘+⬇</kbd> ), the input value will be changed by `0.1 * step`
