Final answer:
The tabindex property can be altered by directly changing it in HTML or by using JavaScript to dynamically set its value, affecting the sequence of keyboard focus.
Step-by-step explanation:
The tabindex property can be changed or the tab order viewed in a few different ways:
- By directly changing the tabindex property in the HTML element to control the sequence of keyboard focus.
- By using JavaScript to dynamically alter the tabindex property.
Though 'View' option and 'Tab Order' might sound like features found in software applications, such options are not standard in web browsers for viewing or setting tabindex in web pages. Therefore, modifying the HTML code or using JavaScript are the usual means of changing the tabIndex.
