Flippage
A tiny app to flip book automatically. Just launch app, specify an interval to flip page in second and direction to flip. Then activate a book reader app and keep reading.
How it works
Once the target app has selected Flippage sends key code periodically as if arrow key has pressed.
Workaround
Unlike the others, Arrow Down is associated with KeyHold event as KeyDown is never invoked. Issue has opened here. robotn/gohook#26
