Issue: 

How to modify the access key of the function in the right-click menu? For example, how to change the default access key C of Copy in the right-click menu to O?
By the way, Ctrl+C here is called the keyboard shortcut or hotkey of the Copy command.

Solution:

  1. Enter the command CUI to enter the Custom User Interface dialog box.
  2. Select [Shortcut Menus →  Context Menu in Default Mode →  &Copy].
  3. Modify from &Copy to C&opy in Name in the Properties dialog box, and then the access key of Copy function will change from C to O(The letter after the & is the access key).
  4. Click Ok to save the settings.
