Yes, you can activate the Old Handwriting browser extension with a keyboard shortcut in the same way as you do for most other extensions:

1. Click the puzzle piece icon in the browser toolbar and select Manage Extensions from the menu.
   
   
    
2. Click on Keyboard shortcuts in the left menu.
   
   
3. Click on the pencil icon in the Old Handwriting AI Transcription section to edit the shortcut.
   
   
    
4. Type in the keyboard shortcut you want to use to activate the extension. You must use a modifier key like shift or control. Pick a shortcut key kombination that is easy to remember and that does not conflict with any existing shortcut used by the browser or another extension. For example: control + H (for Handwriting).
