mfc accelerators Ctrl + doesn't work

I have mfc application where I defined keyboard ACCELERATORS It works fine when I use alphanumeric characters, but I want to define an accelerators that zoomin/zoomout while pressing on the keys +/- so I defined it as the following and it works fine

 ID1 ACCELERATORS DISCARDABLE
 {
   "+",  ID_ZOOMIN ,  ,ASCII, NOINVERT      
   "-",   ID_ZOOMIN ,ASCII, NOINVERT        
 }

Now I added a text box that can accept "+/-" as charcters but pressing on them now function as zoomin/zoomout and the characters "+/-" are not typed so I changed my implementation to have the "zoomin/zoomout" functionality only works while the control button is pressed 

 ID1 ACCELERATORS DISCARDABLE
 {
   "+",  ID_ZOOMIN ,  ,ASCII, CONTROL, NOINVERT      
   "-",   ID_ZOOMIN ,ASCII, CONTROL, NOINVERT        
 }

but still pressing +/- or Ctrl + +/Ctrl + -" function as "zoomin/zoomout" and the +/- characters are not typed Note: changing ASCII to VIRTKEY doesn't solve the problem

Any ideas??

I've just tested with my Windows laptop. It seems ASCII accelerators don't support the CONTROL modifier.

Use VIRTKEY instead.

 ID1 ACCELERATORS DISCARDABLE
 {
   107,  ID_ZOOMIN,  VIRTKEY, CONTROL, NOINVERT      
   109,  ID_ZOOMOUT,  VIRTKEY, CONTROL, NOINVERT        
 }

Or specify VK_ADD for +, VK_SUBTRACT for -.
