I upgraded my cheap mouse with this button remapping app

Most premium computer mice aren’t just about better build quality and reliability. They also offer something cheaper alternatives lack, which is powerful customization software. In fact, it’s a big reason most power users are willing to pay a premium on mice from brands like Logitech, Razer, Corsair, and similar others.

The thing is, you don’t necessarily have to spend $60 or $80 on a mouse just to get that software. MouseKey is a free button remapping app that lets you remap buttons of virtually any mouse. I tried it with my cheap $7 mouse, and it worked brilliantly.

MouseKey makes my cheap mouse feel like a premium one

Each button does six different actions now

The mouse I use currently has five buttons: the standard left and right clicks, a clickable scroll wheel, and two side buttons. By default, those side buttons only work as Back and Forward. That's handy, but sadly, there’s no way to customize them because the manufacturer doesn’t offer any companion software.

MouseKey is a simple app that lets you remap the buttons of any mouse. Out of the box, it offers 22 useful actions like copy, paste, undo, redo, save, mute, select all, hide windows, volume up/down, and more. And you're not limited to those pre-defined actions. You can create your own custom hotkeys. These can be keyboard shortcuts or even specific text strings.

For instance, I’ve configured my middle-click button to perform three left-clicks in quick succession. This way, I can select an entire paragraph with a single click. I’ve also assigned the middle-click long press to capture the screenshot since it’s something I need often.

The best part about MouseKey is flexibility. It lets you assign different actions for different click patterns on the same button. You can assign separate commands for a single click, double click, triple click, quadruple click, quintuple click, and a two-second hold. That means every button on the mouse can do up to six different actions. And yes, that also includes the left, right, and middle buttons. So with five buttons and six possible actions for each, MouseKey lets me do 30 different things with my humble, inexpensive mouse. Of course, if your mouse has more buttons, it's even more fun.

App-specific profiles make it even more useful

It adapts to what I’m doing

Remapping mouse buttons is useful, but what really makes MouseKey special is profiles. With them, you can set the same button to do completely different things depending on the app you’re using.

For example, I’ve set one of my side buttons to open a new tab when I’m using Brave. But that same button becomes a shortcut for Select All when I’m in Word. Even better, I don’t have to switch profiles manually. MouseKey automatically changes them depending on the app I’m using. The only setup I need to do is tell MouseKey which profile to use for a specific app. This is the kind of control you usually only see in high-end gaming mice, and MouseKey brings that same level of convenience to any mouse.

Also, profiles aren’t limited to just button remapping. You can also set different pointer and scroll speeds for different profiles. This way, I can use a slower pointer speed in Photoshop while keeping a faster speed for browsing and PDFs.

MouseKey is all about ease of use

It’s unlike anything I’ve used before

What makes MouseKey so easy to recommend is the ease of use. I’ve tried similar tools like X-Mouse Button Control and MouseButtonsMapper before, but they both have an outdated interface and confusing options. MouseKey is nothing like that. Remapping mouse buttons only takes three steps. Selecting the button, choosing a click pattern, and assigning an action. I also like how every remapping can be enabled or disabled using simple toggles.

It even does a great job of letting me know when a shortcut is triggered. Whenever I use one of my custom mouse shortcuts, for instance, it gives subtle visual and audio feedback. I find it handy because, with so many configurations, it’s sometimes easy to forget why double-clicking the right mouse button performs an Undo command.

It’s the cheapest mouse upgrade I’ve ever made

MouseKey is great, but it isn’t completely free. The free version lets you create up to three button remappings, which is enough to get a feel for what the app can do. But if you want unlimited remappings and access to app-specific profiles, you’ll need the Pro version.

Thankfully, it's a one-time purchase that costs $6.99. Funnily enough, that’s exactly what my mouse costs. That means I’ve spent $14 in total for the kind of customization that you only see in mice that typically cost $50 or more. The best part is I can use MouseKey with any mouse I upgrade to in the future.
