VBA activate send keys when toggle button is pressed

[decadence]

Hi, Is it possible to press a toggle button to activate a send key button then press that button (i.e. directional buttons - Up Key, Down Key, Left Key, Right Key which will have a macro assigned to each) but be able to repeat the key button press as many times as desired until the toggle button is pressed again to de-activate the key buttons? Any help would be greatly appreciated I hope this makes sense.

I can create a toggle button in xml but I'm not sure how to get round this in VBA

Example:
Toggle Button On

• 
  Left Key
  Left Key
  Left Key
  Left Key
  Left Key

Toggle button Off
