Description of Problem:

This was found on Mono WinForms revision 133896.

In Windows I can press ToolBarButtons and drop down ToolBarButtons with the keyboard*.  I cannot do this in Mono on Linux.

Steps to reproduce the problem:

1.  Run the attached (IronPython) test case application
2.  Press the right arrow to focus on the "Push Button" button
3.  Press Enter (or Space) (which should press the button and update the GUI label)
4.  Press the right arrow to focus on the "DropDownButton" drop-down button
5.  Press the down arrow (which should drop down the "DropDownButton" menu)

Actual Results:

Pressing enter when a push button is focused has no effect

Pressing down when a drop down button is focused has no effect

Expected Results:

Pressing enter when a push button is focused should have the effect of clicking it.

Pressing down when a drop down button is focused should drop down the menu.

How often does this happen? 

Every time.

Comments:

* - The "Toggle" toggle button on the ToolBar doesn't appear to be toggled on or off with the keyboard in Windows.

This bug is bad for the accessibility and accessibility tests.
