Open Settings → Accessibility → Mouse, enable Mouse keys, and use the numeric keypad to move the pointer. Select a mouse button before pressing 5 to click. Test movement and clicking on a harmless window before using the feature as your main input.
Check the keyboard before changing settings
Find the numeric keypad on your keyboard. It is the group of number keys separate from the main row. The feature depends on the keypad’s key events. A compact keyboard can require a different layout or an embedded keypad accessible through a function key. Consult its manual and try an external keyboard if you have one. Keep any working mouse or trackpad available during the first test so you can recover easily if the keypad behaves differently from what you expected.
Open a blank document and type a few numbers using the keypad. This confirms that Windows receives input from that group of keys. Check whether the keyboard has a Num Lock indicator and note its state. If the keypad is wireless, confirm that it has charge and a stable connection before testing the feature. Our Windows Bluetooth pairing guide covers verifying a wireless input device before changing accessibility settings. A working connection is an important baseline.
Enable Mouse keys and move the pointer
Open Settings, select Accessibility, and look under Mouse for Mouse keys. Turn it on. Microsoft’s Mouse keys instructions list the available actions. On the keypad, 8 moves up, 2 down, 4 left and 6 right. The corner keys move diagonally. Use a wide blank area for the first movements. Give yourself space to see the direction clearly, particularly if the pointer is near a window edge.
If nothing moves, inspect the Mouse keys options and check whether the feature is configured to work only with Num Lock on. Toggle that key once and repeat the same movement. Take care not to infer that the number row is equivalent. If you are using an embedded keypad, check its own activation control. Once you have movement, test each direction and confirm the pointer can reach a visible toolbar without moving off the intended screen.
Choose a button before clicking
The keypad slash selects the left button, the minus sign selects the right button, and the asterisk selects both. Press 5 to perform the selected click. Start by selecting the left button, moving over a harmless text field and pressing 5. Enter a few letters to confirm the field received focus. Next select the right button and press 5 over a blank area to see a context menu. Press Escape to close the menu, then select the left button again.
The selected button can persist between actions. If a normal click suddenly opens a context menu, reselect the left button before assuming the application is broken. Microsoft’s instructions also list the keypad plus key for double-clicking. Test it on a local folder you recognize. If one application ignores a click, repeat the same command in a simple app to determine whether the issue is general or specific to the first window.
Practice dragging without risking a file
In a scratch window, move the pointer over a title bar or another item that is safe to move. Select the left button, use the keypad zero key to hold it down, then move the pointer using the direction keys. Use the decimal key to release the button. Practice with a window first so there is no chance of moving an important file to an unknown folder. Check where the pointer and window ended up before starting a second drag.
For files, using the keyboard can be simpler than dragging. Select an item, use the ordinary copy shortcut, open the intended destination and paste. This makes the destination explicit. Our clipboard guide explains the difference between the current copy and historical items. Use file or folder commands only after confirming the correct window is active. If you accidentally hold a button, release it before trying another method.
Adjust speed and check multiple displays
Review the pointer speed and acceleration controls exposed near the Mouse keys toggle. Start with a comfortable setting that lets you approach a small button without overshooting. Test both a short move within a dialog and a longer move across the desktop. If the interface offers modifier keys for changing movement speed, test them in a blank area. A good setting lets you move across the screen and still select a small target without alternating constantly between two devices.
If you have several screens, first confirm that Windows arranged them in the same order as the desk. Our dual-monitor guide shows how to identify each screen and adjust shared edges. Move the pointer across the intended boundary with the keypad and back again. If it stops, try a different height along the edge. Correct the screen arrangement rather than increasing pointer speed to compensate for a boundary that is in the wrong place.
Keep a recovery route available
Write down how you turn the feature on and off and how you switch back to a normal keypad. If you share the device, practice returning it to its original settings. Keep one known input option available while changing keyboards. When working in a remote session, test whether key events reach the remote PC or stay with the local computer. Do this first in a blank window so no unintended actions happen while you are figuring out which environment received the input.
You can also combine Mouse keys with ordinary keyboard navigation. Tab moves focus between many controls, Enter activates a focused button, and Escape closes various menus or dialogs. These controls remain useful even when moving the pointer is possible. Try a short workflow such as opening a document, selecting a menu and closing the window. Note when moving the pointer helps and when the keyboard shortcut is quicker. Keep the steps that make the device easier for you to use.
To rehearse a recovery, turn the feature off and back on using only controls you can reach reliably. Use a blank workspace to check movement, click selection and release. A short practice run makes it easier to spot an unexpected keyboard mode when your usual mouse stops working.
When choosing an external keypad, check the layout before depending on it. Some compact designs omit a separate decimal or place arithmetic keys behind a mode switch. If a key serves two purposes, practice the mode change with Mouse keys off first. Then turn the feature on and confirm that every action you need is available from the same arrangement.
Frequently asked questions
Can I use the number row instead?
Use a numeric keypad or a supported embedded keypad. Test how the keyboard exposes it to Windows.
Why does 5 open a context menu?
Select the left button again with keypad slash and retry. A right-button selection can persist.
Can I keep my ordinary mouse connected?
Yes. Keep a working device available while testing and use the input method that suits each task.
