You can set the keys specified in the Base tab.
ex. 1) If you set the number key '1' to 'F1' on a 60% layout, pressing '1' will activate 'F1'.
ex. 2) In the case of layouts like WKL or HHKB where there is no Windows key or Control key, you can assign them to another key (usually the Caps Lock key) for use.


You can set keys beyond the standard layout, such as "Numpad," "F13-F24," "ESC ~," and so on.

You can set special keys related to functions like volume control, web media playback, brightness, and more.

In other words, use this when you want to input a key combination with the Fn (Function) key.
MO (Momentary Layer Toggle) 1-3: This is functionally the same as the commonly known Fn key; holding this key down activates layers 1 through 3.
DF (Default Layer Switch) 1-3: This switches the main layer to Layer 1 through 3.
To use this function, you must delete the "▽" key in the corresponding layer and assign a base key for normal input.
TG (Toggle Layer) 1-3: Similar functionality to MO; pressing this key once changes to Layer 1 through 3 for use, and pressing it again returns to the main layer.

You can configure and use XBox Controller input.
