KeyBinding erroneously fired when modifiers are pressed

[kaspnilsson]

Description

I'm using the IronA11yKeysBehavior in my project, and I have a key binding to 'c'. I expect it to be fired when no modifiers are supplied, and for the browser to handle copy natively when ctrl+c or cmd+c are pressed. Instead, the key binding to 'c' is called any time something that isn't explicitly bound with a different key binding is pressed, regardless of other keys/modifiers. Is this expected behavior?

In some keyboards the user will have to use modifiers to type certain characters (e.g. the french keyboard requires the user to press Shift to type a number).
