@davidrevoy One thing you could do to turn this into something more like a MacroPad is to bind your NumPad keys to shortcuts in a script for an AutoHotKey port for GNU/Linux (for example, AHK_X11 ( https://github.com/phil294/AHK_X11 ) is what I used, and should work for any X11-based distro). The NumPad keys don't get registered by anything other than the AHK interpreter, so you don't have to worry about them accidentally triggering some other action they were bound to.
