Keybinding in 1.3

[linuxgurugamer]

The notes say the following:

Quote

• KeyBindings primary and secondary have changed from KeyCode to ExtendedKey so they cannot be used in Input.GetKey, Input.GetKeyUp, Input.GetKeyDown. instead mods should use the methods GetKeyDown, GetKeyUp & GetKey of the KeyBindings class.

and, looking at the KeyBinding class, I see KeyCodesExtended for primary and secondary.

and, I figured out that to see a Keydown, the following seems to work:

GameSettings.MODIFIER_KEY.GetKeyDown()

but, how can I tell if it was the primary or secondary which was pressed?
