Shortcuts on a laptop?

I am new to renoise and loving it. The only thing that’s limiting me is that all the shortcuts to selects instruments and ovtave up and down are on the numpad. I know i can remap them but was wondering if there is laptop mapping somewhere that people use and everybody knows about.

instrument change: option + up/down (mac)
octave change: command + [ or ] (up or down)
