These keys are manufactured by Signature Plastics and are inspired by Vim, the ultimate text editor. The Vim Caps Lock replacement key has been around a while but is usually only available sporadically. While these keycaps are great, I wanted navigation keys in the the style of the original ADM-3A terminal too.
Since they didn't exist, I asked Signature Plastics to make them for me. I bought extras so I could share them with other Vim nerds. Since I am a filthy capitalist, I am charging money for them. The keycaps are currently only available in SA and DSA profiles and can be purchased below using PayPal's checkout process. Shipping is included in the price, but I reserve the right to charge a little extra if the shipping cost becomes too high. If you have any questions or trouble ordering, please let me know by email.
