## Toggle Layer
The "toggle layer" behavior allows you to enable a layer until the layer is manually disabled.
### Behavior Binding
- Reference: `&tog`
- Parameter: The layer number to enable/disable, e.g. `1`
Example:
```
&tog LOWER
```
"Toggle layer" for a :
```
#define DEFAULT 0
#define NAVI 1
#define NONE 0
/ {
keymap {
compatible = "zmk,keymap";
default_layer {
bindings = <
&tog NAVI &kp KDIV &kp KMLT &kp KMIN
&kp NUM_7 &kp NUM_8 &kp NUM_9 &kp KPLS
&kp NUM_4 &kp NUM_5 &kp NUM_6 &kp KPLS
&kp NUM_1 &kp NUM_2 &kp NUM_3 &kp RET
&kp NUM_0 &kp NUM_0 &kp DOT &kp RET
>;
};
nav_layer {
bindings = <
&tog NAVI &kp KDIV &kp KMLT &kp KMIN
&kp HOME &kp UARW &kp PGUP &kp KPLS
&kp LARW &none &kp RARW &kp KPLS
&kp END &kp DARW &kp PGDN &kp RET
&kp INS &kp INS &kp DEL &kp RET
>;
};
};
};
```
It is possible to use "toggle layer" to have keys that raise and lower the layers as well.
