I can handle the software part. I just want some ideas on how I can change the keys via a cheap and less-effort method. It is not a Peripheral keyboard, just the one integrated with my laptop.
Conclusion: Because numerous people have said it now, I will try to just build a muscle memory of it like I did w/ Qwerty and may not use stickers. Thank you everyone.
You don’t. Seriously. The point of an ergonomic keyboard is to touch-type. You won’t learn to do that if you look at your keyboard.
Print your keyboard layout on a sheet of paper, and hang it next to your monitor. Now when you want to type a character, look it up on your sheet, and without looking at your fingers, type it. Try to remember the position like “left index finger, two lines above the rest line”.
