Use the “Find” shortcut instead: CTRL+F. When you have a window open and want to find something, press CTRL+F and a “Find” window appears. Now, type part or all of a word or number that you are looking for, and press Enter. The window will automatically scroll to the keyword you entered. Even better- as you are typing, it will find the word and highlight it!
*Note- if you do this in Outlook, CTRL+F will open a window to forward the email in your preview screen, not open a find window.
