Best Keybinds for Leaning Without ADS in Rainbow Six Siege

Rainbow Six Siege’s Year 11 Season 3 update, launched September 1, 2026, brought a redesigned input-remapping flow for mouse and keyboard. Ubisoft says it supports multiple bindings and Press, Hold, and Toggle interaction types. That makes it easier to test a second lean key or a different press behavior, but it does not make one layout best for everyone. For leaning without aiming down sights (ADS), start with separate, easy-to-reach keys—often Q and E—then adjust if they conflict with movement, hand position, or mouse grip.

Hip-fire leaning lets you shift your view around cover before committing to ADS. It is useful for checking an angle or moving while keeping your weapon ready, but it does not make you harder to hit automatically, and leaning can expose more of your body depending on your position. A good bind should be fast and reliable, not simply popular.

Recommended starting layout: Q and E

On a standard keyboard, Q and E sit beside the WASD movement cluster and are easy to reach without moving your hand far. Assign one direction to each key, then test whether your fingers can lean while strafing and moving backward. This layout keeps both lean actions on the keyboard, leaving the mouse focused on turning and aiming.

SetupGood fit forMain trade-off
Q = lean left; E = lean rightMost players using a standard WASD hand positionThose fingers may already be busy with nearby movement or utility keys
Two mouse side buttonsPlayers with a mouse that has two comfortable thumb buttonsThumb presses can disturb aim; mouse buttons may already be assigned
One keyboard key and one mouse buttonPlayers who strongly favor one lean direction or have a one-button mouseThe two directions feel less symmetrical
Alternative nearby keyboard pairPlayers whose hand shape or other binds make Q/E awkwardMay create conflicts with gadgets, stance, or movement actions

Q and E are a sensible baseline, not a universal competitive setting. If either key makes you lift a movement finger at the wrong moment, test a different pair before building muscle memory. Avoid placing lean on a key that you must press frequently for a gadget, melee, or stance change unless you have reassigned the conflicting action elsewhere.

How to change the lean keys

From the main menu, open Options, then go to Controls and use the current keyboard-and-mouse remapping screen or diagram. Find the entries for leaning left and leaning right, then assign the keys or mouse buttons you want. The updated remapping flow supports multiple bindings; if the lean action offers an interaction type, choose Press, Hold, or Toggle and test what it does in your build. Apply or save the changes using the prompt shown on screen, then check them in a low-pressure practice mode before a live match.

The options menu was overhauled with the Year 11 Season 3 update, so older instructions that name a specific submenu may no longer match the screen exactly. Follow the current on-screen prompts. If the game displays a conflict or the new key does not appear in the mapping overview, resolve the duplicate assignment and confirm the change saved before testing.

Choose a bind for your hand and play style

Keep Q/E if movement stays comfortable

Stay with Q/E when you can reach both keys while maintaining WASD movement and when you do not routinely need those keys for another action. This familiar layout is easy to remember, and each lean direction has its own key. Practice the combination you actually use: strafe left while leaning right, reverse the pairing, and add backward movement. If any combination feels cramped, the issue is the fit of the layout—not a need to press faster.

Try mouse side buttons if your keyboard fingers are overloaded

If your mouse has two thumb buttons and pressing them does not jerk your aim, you can assign one to each direction. This can leave more keyboard fingers free for movement, but it moves both lean inputs onto the hand that controls fine aim. Test small, precise mouse movements while pressing each side button. If your crosshair jumps or your grip tightens, keep the lean keys on the keyboard or use a mixed layout.

Use a mixed layout only when it solves a real problem

One lean key on the keyboard and one on a mouse button can suit a player who favors one side or has only one comfortable mouse button. The cost is that each direction has a different reach and feel. Do not choose a mixed arrangement just because it looks convenient on a keybind chart; choose it if it remains consistent in both quick checks and longer practice sessions.

What to avoid when rebinding

  • Do not bind both directions to one key. Separate inputs make left and right actions predictable.
  • Avoid keys that interrupt movement. Test leaning while strafing, backing up, and changing direction.
  • Check every conflict. A lean key should not accidentally trigger a gadget, melee, stance change, or interaction.
  • Do not assume a controller recommendation applies to PC. Controller lean behavior and keyboard-and-mouse bindings are handled differently.
  • Do not mistake hip-fire lean for ADS. The ability to lean without aiming does not mean every weapon action or sight behavior is identical in both states.

Check that the setup works before a match

In a practice environment, stand behind a piece of cover and verify three things: each key produces the intended lean direction; releasing the key returns you to a neutral position if the current input behavior is hold-based; and your movement and aim remain controlled while you combine lean with strafing. Then repeat from the opposite side of cover. This is a functional check, not a test of whether one keybind improves win rate.

If a bind does not respond, revisit the current remapping screen and confirm the new input appears in the keyboard-and-mouse overview. Check for a duplicate assignment and make sure you are testing on keyboard and mouse rather than a controller profile. If the lean works while aiming but not from hip fire, confirm you are using the PC keyboard-and-mouse controls and consult the current in-game control descriptions; control behavior can differ by input method and may change in a later update.

Bottom line

Start with Q for lean left and E for lean right if they are comfortable and conflict-free. Move both actions to mouse side buttons only if you can press them without disturbing aim; use a mixed setup only when it fixes a specific reach or hand-position issue. Ubisoft’s September 2026 accessibility update describes the new remapping flow, multiple bindings, and Press, Hold, and Toggle options. Ubisoft’s PC input update confirms that keyboard-and-mouse players can lean without first entering ADS. Use the current game menu for the exact controls; choose your keys by testing comfort and conflicts on your own setup.
