This page lists all the shortcuts used in the 4D Design environment (except for standard "system" shortcuts, such as Ctrl+C/Command+C for the Copy command).
To modify a shortcut, you can select/deselect the item to modify (Shift, Alt or letter key) in the list. You can also double-click on a shortcut to configure it using a specific dialog box.
Note that each shortcut implicitly includes the Ctrl (Windows) or Command (macOS) key.
If you edit this list, your custom shortcuts settings are stored in a 4DShortcutsvXX.xml file, created at the same level as the user preferences file. Hence, each time 4D is updated your keyboard shortcut preferences remain.
