Hello everyone!
I've recently made two pull requests on Silex that should add common keyboard shortcuts, as well as a floating window allowing you to check what shortcuts there are.
Here is the list of shortcuts.
- Native ones:
    
Ctrl+Z: Undo 
    Ctrl+Shift+Z: Redo 
    Ctrl+C: Copy 
    Ctrl+V: Paste 
    S: Next Component 
    W: Previous Component 
    D: Enter Component 
    A: Exit Component 
    Backspace: Delete Component
 
- New ones:
    
Alt+S: Open Settings 
    Alt+P: Open Publish Modal 
    Alt+F: Open Fonts 
    Tab: Preview Mode 
    Shift+K: Shortcuts Help 
    Shift+L: Layers 
    Shift+A: Blocks 
    Shift+N: Notifications 
    Shift+P: Pages 
    Shift+S: Symbols 
    Escape: Close Panel
 
Keyboard choosing constraints:
- We should prefer lettered shortcuts (ex: 
Shift+X, and not Shift+%), because of keyboard layout differences. 
- We have to be careful not to conflict with the browsers' default shortcuts.
 
What shortcuts do you want to see inside Silex? 😄
