## Esc and `~ on a key
## Esc and `~ on a single key
Use `GRAVE_ESC` or `KC_GESC` in your keymap. `GUI`+`GRAVE_ESC` results in `` ` `` and `SHIFT`+`GRAVE_ESC` results in `~`.
Note that this will break the CTRL+SHIFT+ESC shortcut to the Windows task manager. Use `#define GRAVE_ESC_CTRL_OVERRIDE` in your `config.h` to get the shortcut back. With this option, `ESC_GRAVE` results in `ESC` if `CTRL` is held, even if `SHIFT` or `GUI` are also held.
See the [Grave Escape](feature_grave_escape.md) feature.
## Arrow on Right Modifier keys with Dual-Role
This turns right modifer keys into arrow keys when the keys are tapped while still modifiers when the keys are hold. In TMK the dual-role function is dubbed **TAP**.

# Grave Escape
Grave Escape is a feature that allows you to share the grave key (`\`` and `~`) on the same key as Escape. When `KC_GESC` is used it will act as `KC_ESC`, unless Shift or GUI is pressed, in which case it will act as `KC_GRAVE`.
| Key | Alias | Description |
|-----|-------|-------------|
| `GRAVE_ESC` | `KC_GESC` | Act as `KC_ESC` normally, or `KC_GRAVE` when GUI or Shift are held. |
There are several possible key combinations this will break, among them Ctrl+Shift+Esc on Windows and Cmd+Opt+Esc on macOS. You can use these options in your `config.h` to work around this:
| Option | Description |
|--------|-------------|
| `GRAVE_ESC_ALT_OVERRIDE` | Always send Escape if Alt is pressed. |
| `GRAVE_ESC_CTRL_OVERRIDE` | Always send Escape if Ctrl is pressed. |
| `GRAVE_ESC_GUI_OVERRIDE` | Always send Escape if GUI is pressed. |
| `GRAVE_ESC_SHIFT_OVERRIDE` | Always send Escape if SHIFT is pressed. |
