Ducky One 3 SF macros and bindings

2025-03-29

I always forget this stuff so putting it here for a reference.

My settings

Caps lock -> Fn
Fn + h -> left
Fn + j -> down
Fn + k -> up
Fn + l -> right
Fn + f -> page down
Fn + b -> page up
Del -> Esc
Esc -> backtick
Fn + Esc -> Esc

To summarize: Caps lock as function (Fn), vim arrow keys, regular backtick/tilda, swap delete to Esc

Guide

1) Switch to a profile other than 1

Fn + Alt + 2 for profile 2

Profile 1 cannot be changed.

You can verify this with Fn + Alt + Esc. The profile number will blink.

2) Caps lock -> Fn

Must use "Key Switch Functions" which is different than macro mode for other key remapping.

• Fn + Alt + k for 5 seconds
• Press Capslock once
• Press Esc to finish

3) Other bindings with macro recording mode

In general:

• Fn + Alt + Tab for 3 seconds to enter recording mode
• Press the key (or key combo) you want to rebind
• Press the new key it should become
• Fn + Alt + Tab to save that macro
• You can continue setting or exit exit recording mode with Fn + Alt + Tab

Example for Fn + j -> down:

• Be in recording mode
• Press Fn and j
• Press down arrow
• Fn + Alt + Tab to save

If you changed Caps lock to Fn, you must use the dedicated Fn key to set your binding.

Example for Del -> Esc:

• Be in recording mode
• Press Del
• Press Esc
• Fn + Alt + Tab to save

Example for Fn + Esc -> Esc:

• Be in recording mode
• Press Fn and Esc
• Press Esc
• Fn + Alt + Tab to save

Notes

The manual says that once you enter recording mode, "Caps Lock or indicator lights will flash slowly". I only see the Fn key turn red on mine.

When you enter macro recording mode the keys you have set macros for will be illuminated.

Here you can see Del,Esc light up because I have these set as macros:

When you hold Fn in recording mode you'll see the keys you have set macros for that lead with Fn illuminated.

So here you can see all the h,j,k,l,f,b,Esc light up because I have Fn + h, Fn + j, Fn + k ... already set:
