### Why is this important?
Scripted mouse-specific event handlers can be used to trigger actions on graphical user interface (GUI) controls. Equivalent keyboard-specific handlers allow individuals who rely on a keyboard or keyboard interface to access the same functionality.
<!-- This is where the code snippet is injected -->
<div id="locSnippet"></div>
### What to do
* Using only the keyboard, make sure you can access all the functionality provided by the mouse event handlers.
* **And**, if there is no equivalent keyboard access, follow the event handler table below to provide the corresponding keyboard event handlers:
<!-- To add a table, use three or more hyphens (---) to create each column’s header, and use pipes (|) to separate each column, add a pipe on either end of the row. -->
<!-- Cell widths can vary, the rendered output should look the same. -->
| Use | with |
| -------------- | ------------- |
| onmousedown | onkeydown |
| onmouseup | onkeyup |
| onclick | onkeypress |
| onmouseover | onfocus |
| onmouseout | onblur |
