Capture shortcuts using SendKeys not working.

Hi, I can use macros in Capture schematics but when I try to use the SendKeys command to create a keyboard shortcut I am getting no response from the system and no error messages. I have checked two sources for examples and both use the same format such as the following I found on the Cadence online support site:

SUB ToggleITC_2
  'MACROMENU Toggle ITC
  'MACROKEY SHIFT+I
  'MACRODESCRIPTION Toggles InterTool Communication
SendKeys "%op{RIGHT}{RIGHT}{RIGHT}{RIGHT}%e~"
END SUB

If I put anything else instead of the Sendkeys line I get the expected results. Does anyone else get this to work?

I am using Orcad Capture 16.6-S061 on Windows 7 x64.
