Final answer:
To remove a split in a document, use a keyboard shortcut such as Alt + W, then S in Microsoft Excel, rather than clicking the Split button, shaking the device, saying 'Remove split', or opening a new document.
Step-by-step explanation:
To remove a split in a document without clicking the Split button under View, you can use a keyboard shortcut. For example, in Microsoft Excel, you can remove a split by pressing Alt + W, then S to toggle the split off. This keyboard shortcut is an efficient method because it saves time and can be done without removing your hands from the keyboard or navigating through the menu with a mouse. Unfortunately, shaking the device or saying 'Remove split' are not valid methods for removing a split in most software applications, and opening a new document would not remove the split from the current one but simply create a new, unsplit document.
