How to set an event function via a style?

I have several GUI control elements of which some are supposed to generate the same action (code-behind function call) on mouse interaction (MouseEnter, MouseLeave).
[edit] I am performing some non style related functionality in my event handlers.
Right now I'm using event attributes in each control:

<Button Name="Button" Content="Button 1" 
    MouseEnter="GeneralMouseEnter" MouseLeave="GeneralMouseLeave" 
    PreviewMouseDown="Button1_PreviewMouseDown" PreviewMouseUp="Button1_PreviewMouseUp" />
<Button Name="NotInteractingButton" Content="Button 2" 
    /><!-- this button has no MouseOver-effects -->
<ToggleButton Content="ToggleButton" 
    MouseEnter="GeneralMouseEnter" MouseLeave="GeneralMouseLeave"  />
<!-- needs to use IsMouseDirectlyOver on the slider knob... -->
<Slider Name="HorizontalSlider" 
    MouseEnter="GeneralMouseEnter" MouseLeave="GeneralMouseLeave" 
    ValueChanged="Slider_ValueChanged" />
<Slider Name="VerticalSlider" Orientation="Vertical" 
    MouseEnter="GeneralMouseEnter" MouseLeave="GeneralMouseLeave" 
    ValueChanged="Slider_ValueChanged" />

Since many controls in this example are calling the same two functions "GeneralMouseEnter" and "GeneralMouseLeave", I'd like to be able to define a style or something similar to encapsulate that behavior.

[edit - clarification]
This is supposed to become a kind of plugin later on.
(Include code and XAML files to any GUI program and set a style on each interactive control element...)

From what I found on the web, I can use EventTriggers like in this example:

<Style.Triggers>
  <EventTrigger RoutedEvent="Click">
    <EventTrigger.Actions>
      <BeginAction TargetName="SomeAction" />
    </EventTrigger.Actions>
  </EventTrigger>
</Style.Triggers>

I don't know though if and how to
