Sorry for the late response.

No it didn't work.

All 4 D-Pad directions still continue to move the screen around with no change in either brush size or coloring.

Xbindkeys refers to the D-Pad as

Left m:0x0 + c:113
Right m:0x0 + c:114
Up m:0x0 + c:111
Down m:0x0 + c:116

Attached is my new config file and adding a .txt extension to it.
