Macs do not have an Insert key. This is generally considered a good thing. A suitable replacement key will vary depending upon the application being used. If you wish to overwrite text then the text to be replaced should be highlighted and then anything typed will replace the highlighted text.
Yes, there is an overwrite mode in Mac Pages, but it’s not as straightforward as in some other word processors. To enable it, you can press the "Insert" key, which toggles between insert and overwrite modes. However, many Mac keyboards do not have an "Insert" key, so this feature may not be readily accessible. It’s often easier to simply delete text and type over it in insert mode.
