## Overview
You can quickly switch between Posting and external editors and pagers.
For example, you could edit request bodies in `vim`, and then browse the JSON response body in `less` or `fx`.
You can even configure a custom pager specifically for browsing JSON.
## External Editors
With a multi-line text area focused, press ++f4++ to open the file in your
configured external editor.
The configured external editor can be set as `editor` in your `config.yaml`
file.
For example:
```yaml title="config.yaml"
editor: vim
```
Alternatively, you can set the `POSTING_EDITOR` environment variable.
```bash
export POSTING_EDITOR=vim
```
If neither is set, Posting will try to use the `EDITOR` environment variable.
!!! tip "Using VSCode or Cursor"
If you want to use VSCode or Cursor, you can set the `POSTING_EDITOR` environment variable to `code -w` or `cursor -w` respectively.
## External Pagers
With a multi-line text area focused, press ++f3++ to open the file in your
configured external pager.
The configured external pager can be set as `pager` in your `config.yaml`
file.
For example:
```yaml title="config.yaml"
pager: less
```
Alternatively, you can set the `POSTING_PAGER` environment variable.
```bash
export POSTING_PAGER=less
```
### JSON Pager
You can use a custom pager for viewing JSON using the `pager_json` setting in
your `config.yaml` file.
For example:
```yaml title="config.yaml"
pager_json: fx
```
Alternatively, you can set the `POSTING_PAGER_JSON` environment variable.
```bash
export POSTING_PAGER_JSON=fx
```
If neither is set, Posting will try to use the default pager lookup rules discussed earlier.
## Exporting to curl
> *Added in Posting 2.4.0*
Open the command palette and select `export: copy as curl`.
This will transform the open request into a cURL command, and copy it to your clipboard.
You can optionally supply extra arguments to pass to curl by setting the `curl_export_extra_args` setting in your `config.yaml` file.
```yaml title="config.yaml"
curl_export_extra_args: "--verbose -w %{time_total} %{http_code}"
```
This will be inserted directly into the command that gets copied to your clipboard, immediately after `curl `,
producing a command like the following:
```bash
curl --verbose -w %{time_total} %{http_code} -X POST ...
```
