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.


Replace the KC_GRV key in your keymap (usually to the left of the 1 key) with QK_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 QK_GESC on her keyboard, the OS will see an KC_ESC character. Now if Mary holds Shift down and presses QK_GESC it will output ~, or a shifted backtick. Now if she holds GUI/CMD/WIN, it will output a simple ` character.

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.


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:

GRAVE_ESC_ALT_OVERRIDEAlways send Escape if Alt is pressed
GRAVE_ESC_CTRL_OVERRIDEAlways send Escape if Control is pressed
GRAVE_ESC_GUI_OVERRIDEAlways send Escape if GUI is pressed
GRAVE_ESC_SHIFT_OVERRIDEAlways send Escape if Shift is pressed
