What Is Multi Action?

Multi Action is a Hall Effect keyboard feature that allows up to four distinct actions to be mapped to a single key, each one triggered at four different points. Where mechanical keys operate as either fully pressed or not, Hall Effect magnetic sensors can detect multiple trigger points within a key. This allows for Multi Action to exist and lets users assign multiple inputs to one key at specific points in the key’s travel depth.

The four trigger points available in Multi Action are:

• Half-press — a partial down press, before reaching the full actuation depth
• Full press — the key reaching its maximum actuation depth
• Half-release — a partial release after a full press
• Full release — the key returning to its resting position

Each of these four phases can be configured independently, and each can fire a different action. Because all four occur in sequence within a single keystroke, the entire chain can be executed without lifting a finger or pressing multiple keys simultaneously.

Dual actuation, an earlier iteration of this concept, allowed two actions to be mapped to a single key, typically one at a half-press and another at full press. Multi Action expands that to four trigger points by including the trigger points when the key is being pressed and released.

Comparing the two configurations in CORSAIR Web Hub makes the expanded functionality of Multi Action immediately clear. With dual actuation, users could adjust the actuation trigger for both points and assign an action to half-press and full press. Multi Action builds on this by supporting four independently assigned actions, a choice between momentary and held behavior for each, and individually adjustable actuation trigger points for all four phases.

Multi Action is configured through CORSAIR Web Hub. The setup process follows:

Step 1 — Select the Target Key

Open Web Hub and navigate to Multi Action Tab. Select desired key to set a Multi Action to.

Step 2 — Set Actuation Points

Under the Actions Actuation Points section, you can set the depth thresholds that define where each phase triggers. The top arrow (green) controls the half-press and full release points. The bottom arrow (orange) controls the full press and half-release points.

For example:

• Half-press at 1.0mm
• Full press at 3.2mm
• Half-release at 3.2mm (on the way back up)
• Full release at 1.0mm (returning to rest)

Step 3 — Assign Actions to Each Phase

With actuation points defined, each phase can be assigned an action. This can be a standard keyboard input (a letter, modifier key, number, etc.), a media command, or a macro. Each phase is configured independently, so they do not need to share any relationship with one another.

Actions can be set as either momentary (indicated by a blue square) or held (indicated by a long blue bar on the key). If an action at the half-press phase is set to hold, it will remain active until the key moves out of the trigger zone and activates the next phase.

Configuration Example

The following example demonstrates a slide cancel combo in Call of Duty: Black Ops 7, executed entirely from a single key.

In this configuration, pressing L-Ctrl through its full stroke and releasing it executes a sprint-into-slide-cancel sequence. This is a popular movement technique in Call of Duty that would otherwise require precise, separately timed inputs across multiple keys. The half-press initiates and holds the sprint, the full press triggers the slide, and the half-release fires the jump that cancels it. The tactical throw on full release adds a fourth action to the end of the chain, demonstrating how Multi Action can string together a complete in-game sequence within a single keystroke.

Multi Action has broad applications across gaming and productivity scenarios. In games with ability chains or combo systems, the need to time a sequence of inputs precisely is replaced by a single keypress. Collapsing multiple actions onto one key also reduces the chance of misclicking keys during high-pressure moments, allowing for more consistent and precise execution.

Multi Action is also a practical tool for compact layouts. On a keyboard like the CLIPPER PRO MINI 60, where physical key count is limited, Multi Action can consolidate inputs that would otherwise require separate keys. It is also worth noting that Multi Action can be paired with Rapid Trigger, which allows the four-phase action sequence to reactivate immediately without requiring a full key reset. Multi Action is part of CORSAIR's expanding Hall Effect feature set and represents one of the more significant ways the technology extends what a single key is capable of.
