QMK

As I understand it QMK lets you edit firmware directly on your PC and upload it to the keyboard. More powerful but more complicated. The only advantage might be custom lighting controls. It seems keychron provides source for all firmwares and qmk software. Rainy does not do this. So this is one advantage to keychron. Still I don't think I will ever care to delve this deep. https://github.com/keychron.

VIA

VIA does what QMK does but through a web site we can load custom JSON for our keyboard. Then we can remap keys, and add macros, etc. All stored on our keyboard so will work with any machine. There is basically a mini computer in our Keyboard that we can control through a web site. Amazing stuff. I don't think I could have adjusted to 75% Layout without it.

Gregs 75% layout

I can't stand anybody elses default 75% layout to make this work here is what I need done on every 75% Keyboard. This mimics the TKL layout much more closely so adjusting is much easier.
  1. Remap button right Key fromn Home to Delete
  2. Remap Next Key Up from PgDn to End
  3. Remap Next Key Up from PgUp to Home
  4. Top Right key on my main rainy is Print Screen. Keychron has dial instead here which I think wight work better for PgUp and Pg Down so remap this dial to PgUp and PgDown. Currently the dial does volume which I have no use for
  5. Remap next top to left by 1 key from Delete to Print Screen. I migt end up moving Print Screen on rainy to match this. I want them all to be consistent.

Step By Step

  1. Go to https://launcher.keychron.com/
  2. Connect to 4700g TV Computer using USB cord.
  3. Select a Key to remap up top
  4. It will keep blinking
  5. Select new function below to assign
  6. It seems to immediately save to keyboard

Changed from

Top right had
Delete - Mute/Volume Up and Down
- Pg Up
- Pg Down
- Home

Changed to

Print Screen - Insert (click)/ Pg Up Scroll Up / Pg Down Scroll Down
- Home
- End
- Delete
This feels more natural to me and more like TKL layout. I use Home/End/Delete like crazy moving them closer on 75% to this location is actually what has made me prefer 75% over TKL.
