There was a question on Disable Command-W in the terminal but is there a way to determine Command-W globally on MacOS? I keep accidentally closing my applications.

Under Keyboard & Mouse on System Preferences there is a Keyboard Shortcuts tab.
To disable ⌘W in Terminal, do the following:
From the menu in the top left corner of the screen, select System Preferences. Click on Keyboard then Keyboard Shortcuts then Application Shortcuts.
Click the + button to add a new shortcut
Select "Terminal.app" for the application, and for the command, type
Close Window(this is case sensitive). In the shortcut box, give it a different shortcut, like ⌘ControlW
Now ⌘W will not close your terminal windows.
Best Answer
Just add a new CMD-W shortcut should override the actual behavior.
