1. Add new tabindex
Explanation:
The “Tabindex” attribute is used in HTML to set rules related to principles of elements focusing. With the help of tabindex, you can allow or prevent elements from being sequentially focusable during the keyboard navigation (by pressing the button “Tab”) and determine their relative ordering for sequential focus navigation.
Instructions:
Click on the plus button “+” next to the “Add new tabindex” title. Input the element’s selector (this element will get a required tabindex value) and define the tabindex number by adding it to the “Set Text” field. Please note: tabindex = 0 and tabindex = 1 are only supported!
tabindex=”0″ means that the element should be focusable in sequential keyboard navigation, after any positive tabindex values. A positive value means the element should be focusable in sequential keyboard navigation, with its order defined by the value of the number. Following the described conditions, tabindex=”0″ is focused before tabindex=”1″.
