*bindgesture* [--exact] [--input-device=<device>] [--no-warn] \
<gesture>[:<fingers>][:directions] <command>
Binds _gesture_ to execute the sway command _command_ when detected.
Currently supports the _hold_, _pinch_ or _swipe_ gesture. Optionally
can be limited to bind to a certain number of _fingers_ or, for a
_pinch_ or _swipe_ gesture, to certain _directions_.
[[ *type*
:[ *fingers*
:< *direction*
| hold
:- 1 - 5
: none
| swipe
: 3 - 5
: up, down, left, right
| pinch
: 2 - 5
: all above + inward, outward, clockwise, counterclockwise
The _fingers_ can be limited to any sensible number or left empty to accept
any finger counts.
Valid directions are _up_, _down_, _left_ and _right_, as well as _inward_,
_outward_, _clockwise_, _counterclockwise_ for the _pinch_ gesture.
Multiple directions can be combined by a plus.
If a _input-device_ is given, the binding will only be executed for
that input device and will be executed instead of any binding that is
generic to all devices. By default, if you overwrite a binding,
swaynag will give you a warning. To silence this, use the _--no-warn_ flag.
The _--exact_ flag can be used to ensure a binding only matches when exactly
all specified directions are matched and nothing more. If there is matching
binding with _--exact_, it will be preferred.
The priority for matching bindings is as follows: input device, then
exact matches followed by matches with the highest number of matching
directions.
Gestures executed while the pointer is above a bar are not handled by sway.
See the respective documentation, e.g. *bindgesture* in *sway-bar*(5).
Example:
```
# Allow switching between workspaces with left and right swipes
bindgesture swipe:right workspace prev
bindgesture swipe:left workspace next
# Allow container movements by pinching them
bindgesture pinch:inward+up move up
bindgesture pinch:inward+down move down
bindgesture pinch:inward+left move left
bindgesture pinch:inward+right move right
```
