The trigger key is the core of Loop’s functionality. It must be held down or pressed to activate Loop’s features, including the radial menu and keyboard shortcuts.

Understanding the trigger key

Loop uses a trigger key to function:
  • For radial menu: Hold down the trigger key and move the cursor in the desired direction
  • For keyboard shortcuts: Press the trigger key together with another key to activate specific actions
  • Configuration: Set in the Behavior tab of Loop’s settings
  • Flexibility: Can consist of one or multiple modifier keys
Many users prefer remapping their Caps Lock key to function as their Loop trigger, as it’s easily accessible and rarely used for its original purpose.

Setting Caps Lock as your trigger key

Caps Lock is an ideal trigger key because of its prominent location and infrequent use. There are multiple methods to configure Caps Lock as your trigger key:

Alternative trigger keys

While Caps Lock is popular, you can use any modifier key or combination as your trigger:
Common single modifier options:
  • Right Control (⌃): Good if you’ve remapped Caps Lock
  • Right Option (⌥): Accessible but may conflict with some shortcuts
  • Right Command (⌘): Easy to reach but conflicts with many system shortcuts
  • Function (Fn): Available on most Mac keyboards
Avoid using Left modifiers as they’re commonly used in standard keyboard shortcuts.
Combining multiple modifiers reduces conflicts with existing shortcuts:
  • ⌃⌥ (Control + Option)
  • ⌃⇧ (Control + Shift)
  • ⌥⇧ (Option + Shift)
  • ⌃⌥⇧⌘ (All modifiers - Hyper key)
Multi-key combinations are less convenient to press but virtually eliminate shortcut conflicts.

Testing your trigger key

After configuring your trigger key:
  1. Open any application window
  2. Hold down your trigger key
  3. Move your cursor to see if the radial menu appears
  4. Try moving in different directions to test responsiveness
If the radial menu appears and responds to your cursor movement, your trigger key is configured correctly!
If the radial menu doesn’t appear, verify that:
  • Loop has accessibility permissions enabled
  • Your trigger key is properly set in Loop’s Behavior settings
  • Your keyboard remapping tool (if using one) is running and configured correctly
