-Please note that as of now, this command only supports viewing the variables. The ability to add new variables, modify existing ones, or delete variables directly from this buffer is not available yet. However, this feature is on the roadmap and will be added in future updates.

+
+- `q`: Close the buffer
+- `e`: Edit the variable

 For now, if you want to modify the global variables, you can do so by using the `HurlSetVariable` command or by editing your `vars.env` file directly.
