# Description Allows custom bindings (non-chord) to send a `edit_mode: vi` mode change via the new `ReedlineEvent::ViChangeMode` Takes https://github.com/nushell/reedline/pull/932 # User-Facing Changes You can now set bindings which change the Vi mode. (This still has the same rules for defining the key-combination: Only modifiers and single keys are supported) To do so send a `vichangemode` event with the `mode` field to set `normal`, `insert`, or `visual` ```nushell $env.config.keybindings ++= [{ name: modechangetest modifier: control keycode: "char_[" mode: [vi_normal, vi_insert] event: {send: vichangemode, mode: normal} }] ```
Nushell core libraries and plugins
These sub-crates form both the foundation for Nu and a set of plugins which extend Nu with additional functionality.
Foundational libraries are split into two kinds of crates:
- Core crates - those crates that work together to build the Nushell language engine
- Support crates - a set of crates that support the engine with additional features like JSON support, ANSI support, and more.
Plugins are likewise also split into two types:
- Core plugins - plugins that provide part of the default experience of Nu, including access to the system properties, processes, and web-connectivity features.
- Extra plugins - these plugins run a wide range of different capabilities like working with different file types, charting, viewing binary data, and more.
