# Description
Add a `keybindings get` command to listen and get individual "keyboard"
events. This includes different keyboard keys (see example of use) on
seemingly all terminals and mouse, resize, focus and paste events on
some special once. The record returned by this command is similar to
crossterm event structure and is documented in help message. For ease of
use, option `--types` can get a list of event types to filter only
desired events automatically. Additionally `--raw` options displays raw
code of char keys and numeric format of modifier flags.
Example of use, moving a character around a grid with arrow keys:
```nu
def test [] {
mut x = 0
mut y = 0
loop {
clear
$x = ([([$x 4] | math min) 0] | math max)
$y = ([([$y 4] | math min) 0] | math max)
for i in 0..4 {
for j in 0..4 {
if $j == $x and $i == $y {
print -n "*"
} else {
print -n "."
}
}
print ""
}
let inp = (input listen-t [ key ])
match $inp.key {
{type: other key: enter} => (break)
{type: other key: up} => ($y = $y - 1)
{type: other key: down} => ($y = $y + 1)
{type: other key: left} => ($x = $x - 1)
{type: other key: right} => ($x = $x + 1)
_ => ()
}
}
}
```
# User-Facing Changes
- New `keybindngs get` command
- `keybindings listen` is left as is
- New `input display` command in std, mirroring functionality of
`keybindings listen`
# Tests + Formatting
<!--
Don't forget to add tests that cover your changes.
Make sure you've run and fixed any issues with these commands:
- `cargo fmt --all -- --check` to check standard code formatting (`cargo
fmt --all` applies these changes)
- `cargo clippy --workspace -- -D warnings -D clippy::unwrap_used -A
clippy::needless_collect -A clippy::result_large_err` to check that
you're using the standard code style
- `cargo test --workspace` to check that all tests pass
- `cargo run -- crates/nu-std/tests/run.nu` to run the tests for the
standard library
> **Note**
> from `nushell` you can also use the `toolkit` as follows
> ```bash
> use toolkit.nu # or use an `env_change` hook to activate it
automatically
> toolkit check pr
> ```

# After Submitting
<!-- If your PR had any user-facing changes, update [the
