There are two ways you can configure the buttons on your gaming mouse. You can use:

• Application detection
• On-board memory

NOTE: For help with choosing between application detection and on-board memory, see answer 360023409833.

Configuring mouse buttons with application detection

Logitech Gaming Software enables you to program different button configurations for each profile on your computer. To learn how to create and assign application-specific profiles, see answer 360023409833.

NOTE: If you're new to Logitech Gaming Software or you want to use only one profile with your mouse, first follow the steps in answer 360023409833 to set up your Default Profile as a Persistent Profile.

To configure your mouse buttons using application detection:

1. Open the Logitech Gaming Software:
   Start > All Programs > Logitech > Logitech Gaming Software 8.x

2. Enable Automatic Game Detection mode by clicking the toggle at the right side of the window.

   

3. Click the glowing mouse buttons.

   

4. Select the profile you want to edit by clicking its icon. The profile will have a blue highlight bar above it when selected (ex. "Default Profile" below).
   NOTE: Logitech Gaming Software will detect some games you've installed and create profiles for them. You can create profiles for other games yourself (see answer 360023409833 for help).

   

5. To edit a button, either:

   1. Drag and drop an existing command onto it.
      NOTE: All commands you've created for that profile will be visible in the Commands list on the left. When you drag a command over the mouse, the configurable buttons will highlight. Choose the button you want to program and drop the command on top of it.
      OR

   2. Right-click on a button and select Edit… This pop-up window will appear:
      
      In this screen, you can assign your button as a:
      

      • Keystroke — Assign a single key press, or a key press with modifiers.
      • Multi Key — Assign a "macro'd" series of keystrokes. (NOTE: You can set up these macros to function both with and without recorded time delays.)
      • Text Block — Create a block of text to be typed out when the key is pressed (either with or without Unicode support).
      • Mouse Functions — Assign a button on your mouse to use any of the available mouse button functions.
      • Media — Set a mouse button to function like a media key you'd typically find on a keyboard.
      • Hotkeys — Use a pre-defined keystroke command.
      • Shortcut — Assign a button to launch a file/folder/drive on your computer.
      • Function — Assign a button to act like a Microsoft function button (ex. to open your web browser).
      
      After you select the function to assign the button, click OK. This will apply the new function and you'll see it named over the button in the window (ex. mouse function "G-Shift" is assigned below).
      

   IMPORTANT: At least one button must be configured as "Left Click" and one as "Right Click" at all times. To reprogram either of these buttons, you'll first have to assign that function to another button.

6. If you want to assign alternate functions to your mouse buttons, make sure at least one is assigned as G-Shift. Whenever a button is assigned as G-Shift, a Normal/G-Shift toggle will display.

   

7. Click G-Shift next to the toggle. The button assignments will display highlighted in green. You can now assign an alternate function to every button on your mouse, which you can then access by pressing and holding the button assigned as G-Shift. See answer 360023409833 for more information on using G-Shift.
   NOTE: Any button assigned as G-Shift can't have an alternate assignment. Also, the G-Shift toggle will only be visible if at least one button is assigned as G-Shift.

8. To reassign a button back to the standard behavior of the mouse, right-click it and select Use Generic.

9. To un-assign a button, either right-click and select Unassign or drag the command from the button to the trash icon.

Configuring mouse buttons in on-board memory

To configure your mouse buttons using on-board memory:

1. Open the Logitech Gaming Software:
   Start > All Programs > Logitech > Logitech Gaming Software 8.x

2. Enable On-Board Memory mode by clicking the toggle at the right side of the window.

   

3. Click the glowing mouse buttons.

   

   The screen will now change to show the button-configuration view.

   

4. On the Select Mode wheel, choose the mode you want to configure.
   NOTES:

   • The G600 has three modes you can select by clicking the different sections of the wheel.
   • Each mode can have its own lighting, pointer settings, and button assignments.
   • You can use any button assigned as the Mode Switch to change between modes (default is G8).

5. To change a button assignment, right-click on a button and select Edit.

6. You can choose to have the button perform either a Mouse Function or Keystroke. When you assign a keystroke to the button, the software retains the modifier presses.
   Example: To assign Ctrl+Alt+3, press and release Ctrl, then Alt, then 3. To remove modifier keys, click the Clear button.

7. Click OK to save your function to the button.

   

8. If you want to assign alternate functions to your mouse buttons, make sure at least one is assigned as G-Shift. Whenever a button is assigned as G-Shift, a Normal/G-Shift toggle will display.

   

9. Click G-Shift next to the toggle. The button assignments will display highlighted in green. You can now assign an alternate function to every button on your mouse, which you can then access by pressing and holding the button assigned as G-Shift. See answer 360023409833 for more information on using G-Shift.
   NOTE: Any button assigned as G-Shift can't have an alternate assignment. Also, the G-Shift toggle will only be visible if at least one button is assigned as G-Shift.
