Mouse bindings are configurable, and there are a number of default assignments
|
|
described below.
|
|
|
|
The assignments are based around a triggering mouse event which may be combined
|
|
with a set of modifier keys to produce an action.
|
|
|
|
By default applications running in the terminal don't respond to the mouse.
|
|
However, applications can emit escape sequences to request mouse event tracking.
|
|
When mouse event tracking is enabled, mouse events are NOT matched against
|
|
the mouse assignments and are instead passed through to the application.
|
|
|
|
You can bypass the mouse reporting capture by holding down the `SHIFT` key;
|
|
that will prevent the event from being passed to the application and allow matching
|
|
it against your assignments as though the `SHIFT` key were not pressed.
|
|
|
|
The [bypass_mouse_reporting_modifiers](lua/config/bypass_mouse_reporting_modifiers.md)
|
|
option allows you to specify an alternative set of modifiers to use for
|
|
bypassing mouse reporting capture.
|
|
|
|
## Default Mouse Assignments
|
|
|
|
*Note: you can run `wezterm show-keys` to show the effective key and mouse assignments*.
|
|
|
|
In the table below, `Triple Left Down` means that the left mouse button is
|
|
being triple clicked and that the event matches the downstroke of the third
|
|
quick consecutive press. `Triple Left Up` matches the subsequent release event
|
|
of that triple click, so for a triple click both
|
|
`SelectTextAtMouseCursor="Line"` and `CompleteSelection` will be triggered in
|
|
that order.
|
|
|
|
NOTE: In the action column, `act` is an alias to `wezterm.action` (to avoid repetition):
|
|
|
|
```lua
|
|
local act = wezterm.action
|
|
```
|
|
|
|
| Event | Modifiers | Action |
|
|
| --------- | --- | ------ |
|
|
| Triple Left Down | `NONE` | `act.SelectTextAtMouseCursor("Line")` |
|
|
| Double Left Down | `NONE` | `act.SelectTextAtMouseCursor("Word")` |
|
|
| Single Left Down | `NONE` | `act.SelectTextAtMouseCursor("Cell")` |
|
|
| Single Left Down | `SHIFT` | `act.ExtendSelectionToMouseCursor("Cell")` |
|
|
| Single Left Down | `ALT` | `act.SelectTextAtMouseCursor("Block")` {{since('20220624-141144-bd1b7c5d', inline=True)}} |
|
|
| Single Left Up | `SHIFT` | `act.CompleteSelectionOrOpenLinkAtMouseCursor("ClipboardAndPrimarySelection")` |
|
|
| Single Left Up | `NONE` | `act.CompleteSelectionOrOpenLinkAtMouseCursor("ClipboardAndPrimarySelection")` |

|
|
| Double Left Up | `NONE` | `act.CompleteSelection("ClipboardAndPrimarySelection")` |
|
|

|
|

|
|
| Single Left Down | `ALT+SHIFT` | `act.ExtendSelectionToMouseCursor("Block")` {{since('20220624-141144-bd1b7c5d', inline=True)}} |
|
|

|
|
| Triple Left Drag | `NONE` | `act.ExtendSelectionToMouseCursor("Line")` |
|
|
| Single Middle Down | `NONE` | `act.PasteFrom("PrimarySelection")` |
|
|
| Single Left Drag | `SUPER` | `act.StartWindowDrag` (*since 20210314-114017-04b7cedd*) |
|
|
| Single Left Drag | `CTRL+SHIFT` | `act.StartWindowDrag` (*since 20210314-114017-04b7cedd*) |
|
|
|
|
If you don't want the default assignments to be registered, you can
|
|
disable all of them with this configuration; if you chose to do this,
|
|
you must explicitly register every binding.
|
|
|
|
```lua
|
|
config.disable_default_mouse_bindings = true
|
|
```
|
|
|
|
## Configuring Mouse Assignments
|
|
|
|
{{since('20200607-144723-74889cd4')}}
|
|
|
|
You can define mouse actions using the `mouse_bindings` configuration section:
|
|
|
|
```lua
|
|
local wezterm = require 'wezterm'
|
|
local act = wezterm.action
|
|
local config = {}
|
|
|
|
config.mouse_bindings = {
|
|
-- Right click sends "woot" to the terminal
|
|
{
|
|
event = { Down = { streak = 1, button = 'Right' } },
|
|
mods = 'NONE',
|
|
action = act.SendString 'woot',
|
|
},
|
|
|
|
-- Change the default click behavior so that it only selects
|
|
-- text and doesn't open hyperlinks
|
|
{
|
|
event = { Up = { streak = 1, button = 'Left' } },
|
|
mods = 'NONE',
|
|
action = act.CompleteSelection 'ClipboardAndPrimarySelection',
|
|
},
|
|
|
|
-- and make CTRL-Click open hyperlinks
|
|
{
|
|
event = { Up = { streak = 1, button = 'Left' } },
|
|
mods = 'CTRL',
|
|
action = act.OpenLinkAtMouseCursor,
|
|
},
|
|
-- NOTE that binding only the 'Up' event can give unexpected behaviors.
|
|
-- Read more below on the gotcha of binding an 'Up' event only.
|
|
}
|
|
|
|
return config
|
|
```
|
|
|
|
Each entry in the mouse binding table can have the following fields:
|
|
|
|
* `event` - the mouse event on which to trigger. Described in detail below.
|
|
* `mods` - the keyboard modifier keys that must be active in order to match the event.
|
|
`mods` have the same definition and meaning as for key assignments and are described
|
|
in more detail in [Configuring Key Assignments](keys.md#configuring-key-assignments).
|
|
* `action` - the action to take when this mouse binding is matched
|
|
* `mouse_reporting` - an optional boolean that defaults to `false`. This mouse binding
|
|
entry will only be considered if the current pane's mouse reporting state matches.
|
|
In general, you should avoid defining assignments that have
|
|
`mouse_reporting=true` as it will prevent the application running in the
|
|
pane from receiving that mouse event. You can, of course, define these and
|
|
still send your mouse event to the pane by holding down the configured
|
|
[mouse reporting bypass modifier
|
|
key](lua/config/bypass_mouse_reporting_modifiers.md). {{since('20220807-113146-c2fee766', inline=True)}}
|
|
* `alt_screen` - an optional field that defaults to `'Any'`, but that can also
|
|
be set to either `true` or `false`. This mouse binding entry will only be
|
|
considered if the current pane's alt screen state matches this field. Most
|
|
of the default mouse assignments are defined as `alt_screen='Any'`, a notable
|
|
exception being that mouse wheel scrolling only applies when
|
|
`alt_screen=false`, as the mouse wheel is typically mapped to arrow keys by
|
|
the terminal in alt screen mode. {{since('20220807-113146-c2fee766', inline=True)}}.
|
|
|
|
The `action` and `mods` portions are described in more detail in the key assignment
|
|
information below.
|
|
|
|
The `event` portion has three components:
|
|
|
|
* Whether it is a `Down`, `Up` or `Drag` event
|
|
* The number of consecutive clicks within the click threshold (the *click streak*)
|
|
* The mouse button; `Left`, `Right`, or `Middle`.
|
|
|
|
A double click is a `down-up-down` sequence where either the second button down
|
|
is held for long enough or is released and no subsequent down event occurs
|
|
within the click threshold. When recognized, it emits a `Down` event with
|
|
`streak=2`. If the mouse is moved while the button is held, a `Drag` event
|
|
with `streak=2` is generated. When the mouse button is released an `Up` event
|
|
with `streak=2` is generated.
|
|
|
|
The mouse event recognizer supports an arbitrary click streak, so if
|
|
you wanted quadruple-click bindings you can specify `streak=4`.
|
|
|
|
| Event | Lua Representation |
|
|
| ----------------- | ------------------- |
|
|
| Triple Left Down | `event={Down={streak=3, button="Left"}}` |
|
|
| Double Left Up | `event={Up={streak=2, button="Left"}}` |
|
|
| Single Left Drag | `event={Drag={streak=1, button="Left"}}` |
|
|
|
|
{{since('20220807-113146-c2fee766')}}
|
|
|
|
You can handle vertical wheel scroll events using the example shown below. The
|
|
`streak` and amount associated with either `WheelUp` or `WheelDown` are set to
|
|
`1` for the sake of simplicity of matching the event; you may use
|
|
[`window:current_event`](lua/window/current_event.md), if to access the actual
|
|
delta scroll value while handling the event.
|
|
|
|
```lua
|
|
local wezterm = require 'wezterm'
|
|
local act = wezterm.action
|
|
local config = {}
|
|
|
|
config.mouse_bindings = {
|
|
-- Scrolling up while holding CTRL increases the font size
|
|
{
|
|
event = { Down = { streak = 1, button = { WheelUp = 1 } } },
|
|
mods = 'CTRL',
|
|
action = act.IncreaseFontSize,
|
|
},
|
|
|
|
-- Scrolling down while holding CTRL decreases the font size
|
|
{
|
|
event = { Down = { streak = 1, button = { WheelDown = 1 } } },
|
|
mods = 'CTRL',
|
|
action = act.DecreaseFontSize,
|
|
},
|
|
}
|
|
|
|
return config
|
|
```
|
|
|
|
|
|
# Gotcha on binding an 'Up' event only
|
|
|
|
If you only have a mouse bind on the 'Up' event and not on the 'Down' event,
|
|
the 'Down' event will still be sent to the running program.
|
|
If that program is tracking mouse inputs (like tmux or vim with mouse support),
|
|
you may experience _unintuitive behavior_ as the program receives the 'Down'
|
|
event, but not the 'Up' event (which is bound to something in your config).
|
|
|
|
To avoid this, it is recommended to disable the 'Down' event (to ensure it won't
|
|
be sent to the running program), for example:
|
|
```lua
|
|
local wezterm = require 'wezterm'
|
|
local act = wezterm.action
|
|
local config = {}
|
|
|
|
config.mouse_bindings = {
|
|
-- Bind 'Up' event of CTRL-Click to open hyperlinks
|
|
{
|
|
event = { Up = { streak = 1, button = 'Left' } },
|
|
mods = 'CTRL',
|
|
action = act.OpenLinkAtMouseCursor,
|
|
},
|
|
-- Disable the 'Down' event of CTRL-Click to avoid weird program behaviors
|
|
{
|
|
event = { Down = { streak = 1, button = 'Left' } },
|
|
mods = 'CTRL',
|
|
action = act.Nop,
|
|
},
|
|
}
|
|
return config
|
|
```
|
