First, I'd want to know what you are trying to do with the keys. The way you have it set up, it is always going to send those mouse buttons, which can get very messy.

Second, there's two different commands. %TriggerMainKey% and %Trigger%. The first only sends the main, unmodified key. The second sends a modified key.

You may want to take a look at my HotKeyNet guide and make sure to take a look at the extra stuff I linked in the "More Stuff" section at the bottom.
