1. The Bottleneck

Friction Point: Navigation Latency & Tremor. Using a mouse to click small UI targets (x buttons, address bars) requires fine motor control that degrades rapidly during fatigue.

2. The Patch

Strategy: Map all navigation intents to chorded keyboard inputs. Result: Reduces input latency by ~400ms per action and eliminates fine-motor tracking.

3. The Configuration

Intent Windows MacOS
New Tab Ctrl + T Cmd + T
Close Tab Ctrl + W Cmd + W
Focus URL Ctrl + L Cmd + L
Next Word Ctrl + Right Opt + Right
Delete Word Ctrl + Backspace Opt + Delete

4. Edge Cases

  • Focus Trap: If Ctrl + L fails, focus is likely trapped in a web-app text field.
    • Fix: Press F6 to cycle focus back to the browser chrome.
  • MacOS Deletion: Standard Mac keyboards lack a forward delete.
    • Fix: Use Fn + Delete for forward character deletion.
