Bluetooth Keystroke Notification

[AgentCPU0]

I'm trying to find an app that gives me notification to Bluetooth HID keystrokes. What I mean is, each time I press a button or tilt a J-stick, I get a small text bubble telling me which button I've pressed. I've got a battery notify app and a Bluetooth notify app that both give me the same type of text I'm looking for, and those pieces of text appear above any app I have open.
