OnAction callback is not invoked using hotkeys

[Vitaly]

Dear all,

I'm trying to perfom custom action on Cut command:

<commands>
<command idMso="Cut" onAction="CutClicked" />
</commands>

It works fine when an user clicks on the Cut button. But when the user
presses Ctrl+X the callback is not invoked and the user is actually cuts
selected cells range.

I would like to have CutClicked callback to be invoked both when the user
clicks the button and uses hotkeys.

How this can be achieved?

Thanks,
Vitaly
