Support Shell Integration For Nushell

[Ktoks]

Problem
I would like to propose Nushell shell integration be supported.

Feature
Ctrl-r, Ctrl-t, etc. . . features be supported - similarly to fzf.

Examples
Ctrl-r - allows the user to search past command uses in $HOME/.config/nushell
Ctrl-t - allows the user to search for files in the current directory

Additional context
I don't know that there is additional context needed.

After using this for a while with Bash and ZSH - I have noticed behavior that leads me to believe that when CTRL-R is pressed - it's just running TV directly on a channel - instead of implementing CTRL-R's behavior - similar to the way FZF or Bash/ZSH/Nushell's default CTRL-R works.

I think this functionality could be more broadly used if it were set up in a way where the user can begin typing a command, hit CTRL-R - an immediately look at the user's current shell history.

As TV stands now - if the user types a partial command and hits CTRL-R - TV fails when you don't have a channel set up for the partial command in the terminal. To get the CTRL-R functionality, the prompt must be empty - or the user has to set up every possible configuration to get the same functionality FZF provides.

Do you want me to put in a separate issue for this?

The behaviour you're describing is I believe the one bound to C-t, but C-r should behave as a regular shell history command. If that's not the case, it's not intended and I'd need to investigate why that happens.

You're right - it's when I use C-t without having a channel for the partial command.
My mistake. I am unsure how I got confused yesterday morning.

No problem, I feel relieved 😊
