How do I set up Hypershift to assign secondary functions on the Basilisk V3 X HyperSpeed?

Problem

You want more functionality without adding more buttons. Hypershift lets each physical button perform a second action while a chosen “shift” button is held. You need clear steps to pick a Hypershift button, assign secondary actions, link them to profiles or apps, and make sure the mappings work even when you switch computers.

Solution

Choose one button to act as your Hypershift modifier, then assign secondary actions to the other buttons in Synapse. Save the setup into a profile, link it to games or apps, and write the essentials to on-board memory so your most important bindings travel with the mouse.

Step-by-step instructions

A) Pick your Hypershift button

1. Open Razer Synapse and select your mouse.
2. Go to Customize.
3. Click the button you want to hold as your modifier. Popular choices: Forward side button or the DPI Shift/Paddle if you prefer a “sniper hold.”
4. In the assignment list, set this button to Hypershift.

B) Assign the secondary actions

1. In Customize, toggle Hypershift view (usually a switch or tab at the top).
2. Click each button you want to change and assign its Hypershift action: keystroke, mouse function, multimedia, macro, Windows shortcut, or app tool.
3. Return to the Standard view to ensure your primary actions remain correct.

C) Create profiles and link to apps

1. Open Profiles in your mouse settings.
2. Create a profile for each game or application, for example Shooter, Editing, General.
3. Use Linked Games or Application Linking to attach a profile to specific executables so the correct Hypershift layer loads automatically.

D) Tune DPI and “sniper” behavior (optional)

1. If your Hypershift button doubles as a sniper hold, go to Performance and create a low DPI stage (for example 400–800).
2. In Customize, assign Switch DPI while pressed to a convenient button under the Hypershift layer so it only engages when held.

E) Save to on-board memory

1. Open the on-board memory or hardware profiles area.
2. Save your must-have bindings (primary clicks, key remaps, DPI stages, and any hardware-compatible Hypershift actions) to a slot.
3. Disconnect from Synapse or move the receiver to another PC to confirm your essential Hypershift actions still work.

F) Test and refine

1. Hold your chosen Hypershift button and press another control to verify the secondary action triggers.
2. Adjust timings for macros if needed and avoid overly long sequences that could be flagged by games with strict input rules.
3. Keep a printable or digital cheat sheet until the layout becomes muscle memory.

Optional methods or tools

• Macros: Record short, reliable macros for common actions like reload plus weapon swap, timeline zoom, or color grading toggles.
• Per-app scroll tilt: Map Tilt Left/Right to horizontal scroll in editing apps, then assign Hypershift-tilt to tool switching or timeline nudge.
• Profile export: Export your profiles to back them up before OS reinstalls or moving to a new PC.

Best practices or tips

• Pick a Hypershift button that is easy to hold without straining. The forward side button is a common, comfortable choice.
• Keep Hypershift actions simple and fast. Short single-key or two-key assignments are more reliable than long macros.
• Limit the number of Hypershift rebinds at first. Start with three or four high-impact actions, then expand as you build muscle memory.
• Maintain consistency across profiles. Reuse the same Hypershift layout where possible so you do not relearn per game.
• Save a Safe hardware profile with standard buttons and sensible DPI so you can quickly recover if you use a shared PC or KVM.

Hypershift doubles the utility of your Basilisk V3 X HyperSpeed without cluttering the mouse with extra hardware controls. By choosing a comfortable modifier and assigning a handful of high-value actions, you unlock faster tool switching, quick macros, and precise sensitivity holds in shooters or creative apps. Linking profiles to games and programs loads the right layer automatically, so your layout feels consistent wherever you work or play.

For the smoothest experience across multiple computers, store essential mappings in on-board memory and keep an exported backup of your full Synapse profiles. Combine Hypershift with a low-DPI hold for precise aim, and use scroll-tilt under Hypershift for horizontal navigation in video timelines or spreadsheets. These small touches add up to a layout that feels custom built for your daily tasks.
