Thanks very much Ellipse!
Got a few things i can't figure out with QMK configurator link found in the manual-video, maybe someone in here can help:
On the FN layer i mapped the arrow keys with mouse up/down/left/right, that works fine, the keys beside the up arrowkey are mapped with left and right click (mouse 1 and mouse 2 i assume), that doesn't work at all.
Is this a known bug and is there a fix to it? Other than that i tried to edit the config.h, but i didn;t find any option in the online configurator (just wanted to edit the polling rate and the simultaneously registered keys)
I tried to compile myself with QMK MSYS and the full source download of the beta configurator, but then it tells me something like there are files, but no qmk in this path. If i copy the xwhatsit folder into the QMK folder MSYS clones from git, i can compile but with lots of errors (beta version mismatch i guess).
If i'm missing something or if anyone figured it out, i would love some help
