The tab key is one of the most important keys on a keyboard. It is used to move the cursor to the next field or option in a dialog box, or to move to the next cell in a spreadsheet. The problem is that sometimes the tab key moves the cursor too far, especially in Excel. If you press the tab key while the cursor is in the first cell of a worksheet, it will jump to the last cell of the sheet. This can be very annoying, especially if you're trying to fill out a large spreadsheet.
There are a few ways to fix this problem. One is to change the way Excel moves the cursor when you press the tab key. You can do this by going to File > Options > Advanced, and then scroll down to the Editing options section. In this section, you'll see an option called "After pressing Enter, move selection." Change this option from "Down" to "Right." This will make Excel move the cursor to the right instead of down when you press Enter.
Another way to fix this problem is to use a different keyboard shortcut for moving to the next cell. Instead of using the tab key, you can use Ctrl + Right Arrow. This shortcut will move the cursor one cell to the right, no matter where it is on the sheet. You can also use Ctrl + Left Arrow to move one cell to the left.
If you often find yourself accidentally pressing the tab key and jumping around in your spreadsheet, you may want to consider investing in a wireless keyboard with a built-in trackpad. This will allow you to keep your hands on your mouse and avoid accidentally pressing keys like Tab.
