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_GRAVE key in your keymap (usually to the left of the 1 key) with KC_GESC. When pressed it will behave like KC_ESC, but with Shift or GUI held it will send KC_GRAVE.

Keycodes

Key	Aliases	Description
KC_GESC	GRAVE_ESC	Escape when pressed, ` when Shift or GUI are held

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
