Dedicated hardware
Some keyboards can remap keys like Caps Lock, Control, or Escape on the keyboard itself instead of through the operating system. If your keyboard supports that, it can be a simpler solution than changing Windows, macOS, or Linux settings.
Advantages
- The mapping can stay with the keyboard even when you connect it to another computer.
- It can work before sign-in or outside the main user session.
- It can be especially useful on managed work computers where OS-level changes are restricted.
Methods
1. Configuration tools and firmware-backed remapping
Some keyboards ship with vendor configuration tools. These usually let you change keys in a visual layout editor and may also cover layers, shortcuts, lighting, and firmware updates.
Some of these tools run on top of vendor firmware, but many modern ones are built on open firmware projects such as QMK, VIA, Vial, and ZMK.
Example devices
2. Hardware switches and built-in modes
Some keyboards expose layout changes directly in hardware. Common examples include DIP switches that swap Control and Caps Lock, swap Backspace and Delete, or change platform mode.
The range of changes is usually narrow, but the setup is fast, stable, and does not depend on background software.
