focus

Type: Boolean

Default: false

By default, Redactor doesn't receive focus on load, because there may be other input fields on a page. However, to set focus to Redactor, you can use this setting:

$R('#content', {
        focus: true
});

focusEnd

Type: Boolean

Default: false

This setting allows to set focus after the last character in Redactor:

$R('#content', {
        focusEnd: true
});
