The cursor
To move the typing cursor to the center of the page in a word processor like Microsoft Word or Google Docs, you can use the alignment tools. Simply highlight the text or place your cursor where you want to start typing, then click the "Center Align" button in the toolbar (often represented by centered lines) or use the shortcut Ctrl + E (Cmd + E on Mac). This will position the cursor in the center of the page, allowing you to type from that point.
