OK I am by no means a keyboard expert so after seeing the list on ordering blanks I am a bit overwhelmed.
How should my order look like if I just want every key in the main typing area in PBT white?
So that would be ~ to BACKSPACE, TAB to \, CAPSLOCK to ENTER, LEFT SHIFT to RIGHT SHIFT, and LEFT CTRL to RIGHT CTRL.
It may depend on what kind of keyboard you have, but for Filco/Ducky/Leopold (Maybe even Das, correct me if I am wrong)
~ to BACKSPACE = row 1
TAB to \ = row 2
CAPSLOCK to ENTER = row 3, (don't forget a pair of homing bar, or bump keys to replace your f and j if you want those)
LEFT SHIFT to RIGHT SHIFT = row 4
LEFT CTRL to RIGHT CTRL = row 4 (depending on what kind of keyboard you have)
see the posts on the previous two pages for listing of key sizes in "units".
To read the SP chart, 301657 DCS - 1.5X ROW 1 - YELLOW (YCJ)
That is part number, DCS is the form factor of the keys (for Filco/Ducky/Leopold and some others) - 1.5 is the unit length (This could be tab key) and it fits row 1, but your tab probably matches row 2).
