HUB Quick Start Guide

Can I customize the side scroll wheel buttons?
The side scroll wheel itself is dedicated to horizontal navigation and cannot be remapped. However, the two buttons adjacent to it are fully customizable via our web-based tool for shortcuts like Copy/Paste or Undo
Does this mouse require any software installation for Mac?
No software installation is needed for basic plug-and-play use. For button customization, you simply visit our website in Chrome/Edge. Note: You must grant "Input Monitoring" permission in Mac System Settings for the web configurator
Is this mouse suitable for small hands?
The EM25 is ergonomically designed specifically for medium to large hands. If you have small hands, you might find it slightly bulky. We recommend checking the dimensions in the product images to ensure a comfortable fit
How does the side scroll wheel help with Excel?
The side scroll wheel allows you to scroll horizontally across columns instantly without using the bottom scroll bar or trackpad. This is a game-changer for accountants and data analysts working with wide spreadsheets, speeding up workflow
