  2. Open Capslox;
  3. Give Capslox permission to use Accessibility as prompted;
  4. If you are using Capslox for the first time, it’s recommended to take a look at the Tutorial, which will gets you started quickly with a simple game.

Usage Notice

When Capslox is running normally, the Caps Lock key will become a modifier button, which providing different functions by combining with other different keys, such as Caps Lock + E / D / S / F is Move Up / Down / Left / Right. Short pressing the Caps Lock key is no longer switching case, but send an Esc. To output an uppercase letter, pressing Shift + Any Letter Key.

If you have swapped some modifier keys, such as Caps Lock and Control, it’s highly recommended restore the setting for the best experience.


We call a system global shortcut as a hotkey.

Capslox uses the following symbols to represent hotkeys:

  • : Caps Lock
  • : Command
  • : Option
  • : Control
  • : Shift

For example: E means Caps Lock + Command + E

Hotkey Rule

Capslox’s key scheme will try to follow a rule: See Command key as “enhanced key”. In other words, if we see the function of Caps Lock + a single key as a basic function, in most cases, we will get an enhanced function if we add a Command key to this basic hotkey, for example: Caps Lock + E / D / S / F is Moving Up / Down / Left / Right, then Caps Lock + Command + E / D / S / F will be Moving Up / Down / Left / Right multiple times.

Window Binding

With Window Binding, you can bind the currently active window to a hotkey, and then activate / minimize the window by pressing this hotkey.

The logic when pressing the activate hotkey is as follows:

  • If the bound window is the currently active window, minimize it;
  • If the bound window exists and is not currently active, activate it;
  • If the bound window doesn’t exist, and its application has other windows, then bind one of them;
  • If the application to which the bound window belongs is not running, then run the application and bind its window.
