Keyboard Shortcuts for Save and Undo

[SwapnilChand]

The keyboard shortcuts for Save (Ctrl + S) and Undo (Ctrl + Z) are not functioning in the visual document editor.

Steps to Reproduce:
Open the visual document editor.
Press Ctrl + Z to undo an action.
Press Ctrl + S to save the document.

Expected Behavior:
Ctrl + Z should undo the last action.
Ctrl + S should save the current document.
