Entered a mode in Neovim (nvim) where every key press is interpreted as a command

I'm new to Mac and nvim, I had to switch for my current role and am using nvim to setup my mac.

I don't know what I did but now every key press is a command and can't type it all. I've tried restarting the terminal reinstalling nvim everything but I can't escape my current mode.

For instance just tapping the "U" key does the "undo" command. SO each key is now just doing a command and I don't know how to reset it.

How do I go back to just being able to type, please help I know it's noob question but I've been using a Windows machine for my entire life and now that I have to switch to a Mac all of a sudden I feel completely out of my element.

This is what my nvim looks like right now

In contrast to most other editors, VIM is working with different modes.

If you start VIM, it is usually in the "normal mode" (you can also see the current mode in the button left corner, where currently "normal" is displayed).

To start typing you can for example press i. This will change the mode to "insert" and will work like you probably would expect from other editors.

In general, VIM takes some time to get used to it, so if you want to use it, I would recommend starting with a tutorial first.
