Add a shortcut to start a new chat

[juanfcocontreras]

It is often common before writing code to start a chat to see how to shape it. Right now, the closest thing is CMD + L, where if I have a piece of code selected, it is automatically added, and if not, the entire current file is added.

The idea would be to have a shortcut like CMD + L that would create a new chat, put the focus on the chat input, but not attach any context. You could also consider a configurable option for CMD + L where, when nothing is selected, the current file is not attached.

Simply to add, if the current file is not added as context with CMD + L, it has been enabled so that with CMD + Enter (previously it was codebase) it is possible to send it when sending the question, so you will always have that possibility.

As RomneyDa mentions here, this changed a month ago through a PR:

I think it would be good to have a setting to enable it or not.
