How do I send a request directly from the Collections pane, preferably using a Mac's Command key in the shortcut?

[unikitty37]

I want to be able to move the cursor a request in the collections pane, and press one button to select it (copying it into the address bar) and send it. There doesn't seem to be a way to do this; I have to press Enter Shift-Tab Enter Tab, which is a major faff. (I tried to get Posting to dump its current config, but there doesn't seem to be a command for that…)

Ideally, I would be able to set this key to ⌘↵, but the docs don't mention how to set the Command key on a Mac. It should be treated as Meta or Super, but the docs don't mention being able to use these keys. I can't use Alt, as the Option key is not treated as an Alt key by default, but works in the standard macOS way for typing accented characters. I can't disable this, especially as it will affect all terminal usage.

Unfortunately, the textual that appears to be available on Homebrew appears to be https://www.codeux.com/textual — which is an IRC client. The docs say to run textual to find out what keys are supported, but don't give any instructions on how to install it.

Is textual a Python thing? If so, this is your periodic reminder that Not Everybody Is A Pythonista, And The Docs Should Not Assume They Are :)

I guess I have multiple questions:

• Is it possible to send a request from the Collections pane with a single keypress, without having to navigate between the collection and the address bar?
• Is it possible to use the Mac's Command (⌘) key in the keymap?
• Is there a way to get posting to dump out the YAML of its current config?
