Feature Request: Customizable Keyboard Shortcuts

Current Issue: Currently, Yaak only supports Ctrl+. (Ctrl + period) for inserting environment variables, and this shortcut cannot be customized. The keyboard shortcuts are also not well documented within the app itself (only available on the website).

Requested Features:

1. Customizable keyboard shortcuts - Allow users to modify existing shortcuts, especially the environment variable insertion shortcut (Ctrl+.)

2. In-app shortcut documentation - Display available shortcuts within the app settings or help section, not just on the website

3. Shortcut preferences panel - Add a dedicated settings section where users can:

   • View all current shortcuts

   • Modify existing shortcuts

   • Set custom shortcuts for frequently used actions

Use Case: Different users have different workflow preferences and may have conflicts with existing shortcuts in their system or other applications. Being able to customize shortcuts would greatly improve the user experience and productivity.

Priority: Medium-High This would significantly improve accessibility and user workflow customization.
