What would be an incorrect expectation of using Ctrl+O?

Using Ctrl+O is a keyboard shortcut commonly associated with the command to open an existing file within most applications, particularly in word processing software. This command typically prompts the user to select a file they wish to access that has already been saved.

Expecting that Ctrl+O would create a new document is incorrect because that action is generally performed using Ctrl+N. Ctrl+O specifically relates to opening files rather than creating them from scratch. This distinction is critical for efficient navigation and operation within software programs.

The other options accurately reflect what happens when using Ctrl+O: it opens previously saved files, allows access to documents stored on the computer, and enables editing of existing files, all of which are in line with the functionality of this shortcut.
