Add configurable mouse and wheel bindings, window move and resize, tab drops, cross-output dragging, and device settings. Adjust display scaling in 0.05 increments. Preserve opposite-edge positioning during scrolling resizes and show rows for edge drops into tabbed columns.

# Input
|
||
|
||
| `input` key | Type | Default | Meaning |
|
||
| --- | --- | --- | --- |
|
||
| `focus-follows-mouse` | boolean | `false` | Focus visible windows under the pointer without raising them or scrolling; click or use keyboard focus to reveal a window |
|
||
| `xkb-layout` | nonempty string | `"us"` | XKB layout |
|
||
| `xkb-variant` | string | `""` | XKB variant |
|
||
| `xkb-options` | string array | `[]` | XKB options |
|
||
| `repeat-rate` | integer > 0 | `25` | Repeats per second |
|
||
| `repeat-delay-ms` | integer ≥ 0 | `600` | Delay before repeat |
|
||
|
||
With focus-follows-mouse enabled, hovering a visible part of a window changes
|
||
keyboard focus without raising it or moving the scrolling viewport. Clicking or
|
||
using directional keyboard focus brings the selected window into view.
|
||
|
||
In Overview (`Super+Tab`), click a window preview or a miniature inside a workspace
|
||
card to activate that exact window. Hover highlights the target; directional
|
||
focus keys move the selection, Enter activates it, and Escape dismisses Overview.
|
||
Clicking a workspace card's background switches workspaces while keeping Overview
|
||
open. Previews follow layout order and use the configured shell font and colors.
|
||
|
||
The touchpad keys `tap`, `natural-scroll` and `disable-while-typing` default to
|
||
`true`. Set `disable-while-mouse-connected #true` to pause a built-in touchpad
|
||
while an external mouse is connected. It defaults to `false` and uses libinput's
|
||
external-mouse policy on supported touchpads, including when a mouse is plugged
|
||
in or removed during the session. The toggle is also in **Settings → Keyboard & mouse**.
|
||
These device settings apply to DRM sessions; nested previews use the host's
|
||
physical input settings.
|
||
|
||
Touchpad `accel-speed` is independent of the mouse setting. It accepts −1.0 to
|
||
1.0 and defaults to 0.0. Both speed controls are available in Settings and reload
|
||
immediately in a hardware session.
|
||
|
||
```kdl
|
||
input {
|
||
touchpad {
|
||
accel-speed 0.0
|
||
disable-while-mouse-connected #true
|
||
}
|
||
mouse {
|
||
natural-scroll #false
|
||
accel-speed 0.0
|
||
// accel-profile "flat"
|
||
left-handed #false
|
||
middle-emulation #false
|
||
scroll-factor 1.0
|
||
drag-threshold 4.0
|
||
scroll-cooldown-ms 150
|
||
}
|
||
}
|
||
```
|
||
|
||
Mouse settings are separate from touchpad settings and reload live. `accel-speed`
|
||
accepts -1.0 to 1.0; `accel-profile` accepts `adaptive` or `flat`, and follows the
|
||
device default when omitted. `scroll-factor` scales application wheel scrolling
|
||
(0.01–100). `drag-threshold` is the distance before a window drag starts (0–100
|
||
logical pixels). `scroll-cooldown-ms` limits repeated wheel bindings (0–5000 ms);
|
||
zero allows each accumulated tick to run its action.
|
||
|
||
Workspace swipes and left/right window-focus swipes follow your fingers and settle
|
||
when released. Up goes to the next workspace on the
|
||
current monitor, down to the previous; left focuses the window to the right,
|
||
and right focuses the window to the left. Workspace swipes skip workspaces owned
|
||
by other monitors and stop at the first/last workspace. Short or cancelled navigation
|
||
swipes slide back; diagonal swipes do not navigate. Navigation pauses while locked, during
|
||
window grabs, or when an application inhibits shortcuts.
|
||
|
||
Assign swipes in **Settings → Keyboard & mouse → Shortcuts** using the same actions and arguments as
|
||
keyboard bindings. Choose a "Customize swipe" button to add an override. The
|
||
gesture keys are `Swipe3Up`, `Swipe3Down`, `Swipe3Left`, and `Swipe3Right`; 4 or 5
|
||
fingers are also supported. Changes reload live:
|
||
|
||
```kdl
|
||
binding keys="Swipe3Up" action="toggle-overview"
|
||
binding keys="Swipe3Left" action="move" argument="left"
|
||
binding keys="Swipe3Down" disabled=#true
|
||
```
|
||
|
||
`spawn` uses a named entry from `commands`, just like keyboard shortcuts. To
|
||
disable a direction in Settings, set its action to `none` and leave Argument
|
||
empty. In KDL, `disabled=#true` removes the default binding. Swipes do not use
|
||
keyboard modifiers or physical key matching. The trigger is automatically
|
||
recognized from its name. Gesture navigation uses native touchpad events in a
|
||
hardware session.
|
||
|
||
Adjust recognition distance in **Settings → Keyboard & mouse**, or with
|
||
`swipe-threshold 80` under `input.touchpad` (integer 16–1000 logical pixels).
|
||
|
||
## Mouse bindings
|
||
|
||
`Super+MouseLeft` drags a window and `Super+MouseRight` resizes it. Both work with
|
||
floating windows and tiled windows in scrolling or tree layouts. Drag a tiled
|
||
window to another window's edge to place it beside that window, or to its center
|
||
to join a tab group. Top and bottom drops into a tabbed column show its windows as
|
||
rows. Drag across monitors to move to the workspace shown there.
|
||
While dragging, right-click to switch between floating and tiling. Scroll or hold
|
||
the pointer at a horizontal screen edge to reach other scrolling columns.
|
||
Escape cancels the operation; releasing the initiating button finishes it.
|
||
Fullscreen windows keep their current layout until you leave fullscreen.
|
||
|
||
Mouse bindings use the same actions, overrides and named binding modes as keyboard
|
||
bindings. Ordinary actions use the current keyboard focus; `pointer-move` and
|
||
`pointer-resize` operate on the window under the pointer. Client popup grabs,
|
||
pointer constraints, shortcut inhibition and session locking take precedence.
|
||
|
||
```kdl
|
||
binding "Alt+MouseLeft" action="pointer-move"
|
||
binding "Alt+MouseRight" action="pointer-resize"
|
||
binding "Super+MouseLeft" disabled=#true
|
||
binding "Super+WheelUp" action="workspace-previous"
|
||
binding "Super+WheelDown" action="workspace-next"
|
||
binding "Super+TouchpadScrollLeft" action="focus" argument="left"
|
||
binding "Super+MouseBack" action="focus-last-window"
|
||
```
|
||
|
||
Buttons include `MouseLeft`, `MouseRight`, `MouseMiddle`, `MouseBack` and
|
||
`MouseForward`, or `mouse:272` through `mouse:287` for Linux mouse button codes.
|
||
Wheel directions are `WheelUp`, `WheelDown`, `WheelLeft` and `WheelRight`.
|
||
Touchpad scroll bindings use the `TouchpadScroll` prefix with the same directions.
|
||
Only a bound scroll axis is intercepted; the other axis still reaches the client.
|
||
High-resolution wheel steps accumulate into ticks. An intercepted touchpad scroll
|
||
keeps its event ownership until the gesture stops, even if modifiers change.
