I'm using an Actipro SplitButton in your Ribbon as follows:
I do an Alt-C (assigned to the tab) and I see the KeyTipAccessText of "K" displayed for the SplitButton, and when I press it the dropdown opens. The problem is that, I can't then seem to find another keystroke to perform the action on the button itself (tried Enter, space, etc.). What sequence of keystrokes need to be performed to get the action tied to the SplitButton to occur?
<actr:SplitButton AutomationProperties.AutomationId="buttonSendTaskCommand" KeyTipAccessText="K" AutoDisableWhenPopupContentIsDisabled="False">
<actr:SplitButton.Style>
<Style TargetType="{x:Type actr:SplitButton}" BasedOn="{StaticResource {x:Type actr:SplitButton}}" >
<Setter Property="Command" Value="{StaticResource SendTaskEmailCommand}" />
<Style.Triggers>
<DataTrigger Binding="{Binding Path=PreferredCommunicationType}" Value="{x:Static om:CommunicationType.Web}">
<Setter Property="Command" Value="{StaticResource SendTaskWebCommand}" />
</DataTrigger>
</Style.Triggers>
</Style>
</actr:SplitButton.Style>
<actr:Menu AutomationProperties.AutomationId="popupSendTaskMenu" AutomationProperties.Name="Send Task Menu">
<actr:Button AutomationProperties.AutomationId="buttonSendTaskAlternate" KeyTipAccessText="A">
<actr:Button.Style>
<Style TargetType="{x:Type actr:Button}" BasedOn="{StaticResource {x:Type actr:Button}}" >
<Setter Property="Command" Value="{StaticResource SendTaskWebCommand}" />

<DataTrigger Binding="{Binding Path=PreferredCommunicationType}" Value="{x:Static om:CommunicationType.Web}">

</actr:SplitButton>
