you want to create an OS modal window. How well this works depends on the OS/window manager/desktop environment. On Wayland it works only if the compositor implements the inhibit-keyboard-shortcuts protocol. On macOS Apple doesn’t allow applications to grab the keyboard without special permissions, so it doesn’t work.

scroll_to_prompt

Scroll to the previous/next shell command prompt

Allows easy jumping from one command to the next. Requires working Shell integration. Takes two optional numbers as arguments:

The first is the number of prompts to jump; negative values jump up and positive values jump down. A value of zero will jump to the last prompt visited by this action. Defaults to -1

The second is the number of lines to show above the prompt that was jumped to. This is somewhat like less’s --jump-target option or vim’s scrolloff setting. Defaults to 0.

For example:
