Create a single key-binding that fires a command every time control is pressed with any number and then passes the number as a parameter?

I need to create hot-keys for every control + number combination and would prefer not to have create ten commands. Is there any way to do this?

If I understand your question, you have a single command, say MyCommand, and you want to fire it if the user presses CTRL+0 through CTRL+9, and give the command a different parameter for each combination.

In that case, just create 10 key bindings in your window, all bound to MyCommand, and give them a parameter:

<Window.InputBindings>
    <KeyBinding Command="MyCommand" Gesture="Ctrl+0" CommandParameter="0"/>
    <KeyBinding Command="MyCommand" Gesture="Ctrl+1" CommandParameter="1"/>
    <KeyBinding Command="MyCommand" Gesture="Ctrl+2" CommandParameter="2"/>
    <KeyBinding Command="MyCommand" Gesture="Ctrl+3" CommandParameter="3"/>
    <KeyBinding Command="MyCommand" Gesture="Ctrl+4" CommandParameter="4"/>
    <KeyBinding Command="MyCommand" Gesture="Ctrl+5" CommandParameter="5"/>
    <KeyBinding Command="MyCommand" Gesture="Ctrl+6" CommandParameter="6"/>
    <KeyBinding Command="MyCommand" Gesture="Ctrl+7" CommandParameter="7"/>
    <KeyBinding Command="MyCommand" Gesture="Ctrl+8" CommandParameter="8"/>
    <KeyBinding Command="MyCommand" Gesture="Ctrl+9" CommandParameter="9"/>
</Window.InputBindings>
