Now that blocks can be selected in Design Mode, it makes sense to add basic keyboard shortcuts for block operations.
Remove : Backspace / Del
Copy : Ctrl + C
Cut : Ctrl + X
Paste : Ctrl + V (Not sure where it would be pasted though. Cursor position? Paste them connected to the bottom of the selected blocks?)
Activate/Deactivate : Ctrl + Shift + A (?)
Duplicate : Ctrl + Shift + D (?) (Same considerations here as for Paste)
New operations:
Deselect : Esc

Copy : Ctrl + C
Cut : Ctrl + X
Paste : Ctrl + V (Not sure where it would be pasted though. Cursor position? Paste them connected to the bottom of the selected blocks?)
