UPDATE 2019-12-04: Since very rarely developer needs actually Dead Keys, I took the liberty to remove the Dead Keys (as I wanted easy Backtick and Tilde).
The modified keys are as follows
Option+äwill result in Caret (
- The key left of 1 now produces Backtick (
`) and Tilde (
~) without Dead state. ← Happy Gmail Section navigating 😉
- Key next to
Backspacenow produces acute accent
(´)and grave accent/backtick (
`) without Dead State
- The same key has Dead Key state with Option (⌥) key.
- Download the EstonianDevNoDeadKeys.dmg file (sorry for the .zip – WP does not allow .dmg files to be uploaded directly)
- Unzip and mount the image
- Drag the
Keyboard Layoutsfolder linked into the DMG
- Add the new layout from Input Sources
