Grave Escape
If you're using a 60% keyboard, or any other layout with no F-row, you will have noticed that there is no dedicated Escape key. Grave Escape is a feature that allows you to share the grave key (` and ~) with Escape.
Usage
Replace the KC_GRV key in your keymap (usually to the left of the 1 key) with KC_GESC. Most of the time this key will output KC_ESC when pressed. However, when Shift or GUI are held down it will output KC_GRV instead.
What Your OS Sees
If Mary presses GESC on her keyboard, the OS will see an KC_ESC character. Now if Mary holds Shift down and presses GESC it will output ~, or a shifted backtick. Now if she holds GUI/CMD/WIN, it will output a simple ` character.
Keycodes
| Key | Aliases | Description |
|---|---|---|
KC_GESC |
GRAVE_ESC |
Escape when pressed, ` when Shift or GUI are held |
Caveats
On macOS, Command+` is by default mapped to "Move focus to next window" so it will not output a backtick. Additionally, Terminal always recognises this shortcut to cycle between windows, even if the shortcut is changed in the Keyboard preferences.
Configuration
There are several possible key combinations this will break, among them Control+Shift+Escape on Windows and Command+Option+Escape on macOS. To work around this, you can #define these options in your config.h:
| Define | Description |
|---|---|
GRAVE_ESC_ALT_OVERRIDE |
Always send Escape if Alt is pressed |
GRAVE_ESC_CTRL_OVERRIDE |
Always send Escape if Control is pressed |
GRAVE_ESC_GUI_OVERRIDE |
Always send Escape if GUI is pressed |
GRAVE_ESC_SHIFT_OVERRIDE |
Always send Escape if Shift is pressed |
