-**Problem**: The body element has `select-none` class (Tailwind) which applies `user-select: none` globally. This prevented copy/paste in the custom UUID input field.
+**Problem**: Two issues prevented copy/paste:
+1. The body element has `select-none` class (Tailwind) which applies `user-select: none` globally
+2. Electron's `setIgnoreMenuShortcuts(true)` was blocking Ctrl+V/C/X/A shortcuts
 
 **Fix Applied**:
 - Added `user-select: text` with all vendor prefixes to `.uuid-input` class
-- Overrides the global selection disable for UUID input fields
+- Removed `setIgnoreMenuShortcuts(true)` from main.js
+- Added early return in `before-input-event` handler to allow Ctrl/Cmd + V/C/X/A shortcuts
+- DevTools shortcuts (Ctrl+Shift+I/J/C, F12) remain blocked
