Remap buttons
The Assignments tab changes what a button does. You can give it another mouse button, a keystroke with modifier keys, a media key, a DPI function, a profile switch or a macro, or turn it off.

Which devices can be remapped
In this release, button remapping works on Logitech and SteelSeries mice. Razer and Corsair devices do not support it yet: their Assignments tab says This device has no configurable buttons. The demo devices show buttons for every brand, so you can try the controls.
Some buttons are marked Fixed. They cannot be changed on that device.
Give a button a new action
Select the mouse under Devices and open the Assignments tab.
Select the button you want to change, either its label on the drawing or its row in the Buttons list.
A panel opens under the row with the heading Assign an action to and the button name.
Select a category: Default, Disable, Mouse, Keyboard, Media, DPI, Profile or Macro.
Choose the action in that category, as described below.
The new action shows in the list and on the drawing straight away. The counter at the top of the Buttons list shows how many buttons you have customised.
To undo a change, select Reset in the panel, or select All default at the top of the list to reset every button.
The categories
Default and Disable
- Default shows the button's factory behaviour, for example Factory behaviour: DPI shift (1200). Select Use default to go back to it.
- Disable makes the button do nothing. Select Disable button.
Mouse
Left click, Right click, Middle click, Back or Forward.
Keyboard
Select the box that reads Click to capture a keystroke.
Press the key combination you want, for example Ctrl + B, then release the keys.
To cancel, select the box again.
You can also build the keystroke by hand under Or build one by hand:. Tick Ctrl, Shift, Alt or Super, choose a Key, then select Assign.
Media
Play / Pause, Next track, Previous track, Stop, Mute, Volume up, Volume down, Calculator or Browser home.
DPI functions
- DPI up and DPI down step to the next or previous stage.
- DPI cycle steps through the stages and starts again at the first.
- DPI shift sets a lower or higher DPI only while you hold the button, often used for precise aiming. Set the value next to Hold for, then select Use DPI shift. To change the value later, select Update shift.
Profile
Cycle profiles switches to the next onboard profile each time you press the button. See Use onboard profiles.
Macro
Pick one of your macros from the list. If you have none yet, select Create a macro. See Record and assign macros.
Software actions and Gearwise running
Some Logitech buttons, such as G-keys, hand their presses to Gearwise instead of acting on their own. For those buttons, Gearwise performs the action itself, so it only works while Gearwise is running. Macros are always played by Gearwise, on every button.
