i don't want to make universal iso/ansi enter key plate, so i have done 2 versions.
Last row will be universal for different layout.
Lshift can be:2.25 or 1.25+1 or 1+1.25
Rshift can be: 2.25 or 1.25+1 or 1+1.25 as well.
for alps plate, i am still doing now, will have as well. PCB will support alps also.
