You can also set a custom key combination in the settings menu.
Click File > Settings and select Keymap in the menu on the left, then scroll down to the Other section and set the preferred key combination for Close Active Editor :

When you double-click on Close Active Editor , a pop-up menu appears that allows you to set a key combination, mouse gesture, or even an abbreviation for the action. If the shortcut is already installed in another place (as in my case with Ctrl-W ), you will receive a notification and cannot install the shortcut until you delete another.
