Open the Help file and locate the line in the Windows Keyboard Shortcuts section about Ctrl+0 (zoom to fit). Notice that it looks like Ctrl+o. This is odd and would be confusing to people. What font has 0 looking like lower case o? Bad font! Do you have control over the font to fix it? We don't have any control in the UI over what font is used for UI elements such as the Help text, so it's not possible for the user to fix it, and it shouldn't look wrong by default anyway.
