Right-click shift modifier acts differently than shift

[John]

When using the right click keypress modifier, in some instances it acts differently than using the shift key directly. I have noticed this mostly when using a virtual machine. If I'm running a virtual machine and I try to right click a key in order to capitalize a letter, it does not work. If I press shift on the on-screen keyboard, and then click on the letter, it capitalizes it as expected.
