RMB on Keyboard and Mouse: What “RMB” Means (Right Mouse Button) and How to Use It

You might see instructions like “Press RMB” in a game, design tutorial, or computer guide and wonder where the “RMB key” is on your keyboard.

Here’s the simple truth:

RMB is not a keyboard key.
RMB means Right Mouse Button — the button you use to right-click.

This guide explains what RMB does, where it is on a mouse and touchpad, how to right-click using only the keyboard, and how to fix common RMB problems.

RMB stands for Right Mouse Button.

You’ll see “RMB” in:

PC games (“Press RMB to aim”)
Tutorials (“RMB click to open options”)

On a normal mouse, the RMB is the right button (under your right index finger).

What RMB usually does

RMB opens a small menu with extra options for what you clicked.

Examples:

Right-click a file → you may see Open, Copy, Rename, Delete
Right-click on the desktop → you may see Display settings, Refresh, New folder

C) How to “RMB click” on a laptop touchpad (Windows laptops)

Laptop touchpads don’t always have a separate “right button,” but they can still do RMB.

Method 1: Two-finger click (most common)

Put two fingers on the touchpad.
Click down (or tap) with two fingers.
That usually acts as RMB / right-click.

Method 2: Bottom-right corner click (common on older touchpads)

Move your finger to the bottom-right of the touchpad.
Press down until it clicks.
That often acts as RMB / right-click.

Method 3: Tap-to-right-click (if enabled)

Some laptops allow:

Two-finger tap = right-click
If it doesn’t work, you may need to enable it in touchpad settings (see Troubleshooting).

D) RMB on a Mac (Mouse or Trackpad)

On Mac, “right-click” is often called a secondary click or Control-click.

Easy RMB methods on Mac

Control + Click (hold Control, then click)
Two-finger click on the trackpad (if enabled in Trackpad settings)
If you use a mouse: choose which side is “secondary click” in Mouse settings

E) RMB using only the keyboard (when you can’t right-click)

Sometimes you can open the right-click menu without touching the mouse.

Windows: Shift + F10

Use the arrow keys to select an item (or click it once with LMB).
Press Shift + F10.
The context menu (right-click menu) appears.

Windows “Menu key” (if your keyboard has it)

Some keyboards have a Menu key (sometimes called the Application key). It opens the same right-click menu in many places.

Mac: Control + Click

If you’re using a mouse or trackpad:

Hold Control and click the item.

F) RMB actions explained (simple and beginner-friendly)

Right-click and hold

On some apps, holding RMB may do something different (depends on the software).
