Drupal 8.x

Hello

I have an exposed field with a button that I want to override.

I tried to override with input-button--submit.html.twig but it affects all buttons of my website. I only want to override the button of my view.

Anyone can tell me how to override a view button ?

Thank you.

I am trying to include a custom template in a MODULE.

This tutorial is helpful getting started...

https://www.drupal.org/docs/8/theming/twig/create-custom-twig-templates-...

But it only shows you how to create a random variable in the controller. When I try to create a template for a custom node type in my module, it can't access the {{ content }} at all. How do I pass {{ content }} into the custom template?

In my case, I have some views within blocks. I'm hoping there's a way to change the block title as it appears, based off what page it sites on. i.e., if website.com/x, then block title = "foo", else block title = "bar". I'd like this to add a little adaptability without make new blocks.

I'm not seeing a way yet - without using javascript. Maybe there's a workaround someone has come up with? 

This may be obvious, but I am new to Drupal thinking and I can't think how I can do the following:
