Informational - Your model 01 keycaps are numbered

For those that have blank keycaps or linear-a keycaps, it is highly likely that you will at some point jumble them or get them out of order. No need to fret, on the inside of each keycap, there is a number telling you the key order. Also, you can use the orientation of that number to help you tell up from down on the key.

It doesn’t matter which keycap set you have, from what I can tell they all seem to be numbered the same.

Here is a layout that shows the numbering scheme.
