Keybind to suppress all keybinds

# Description of the new feature/enhancement

We have a lot of programs like vim or others which could have keybinds that map to the same which is in terminal the keyboard is kind of limited for all the possible keybinds to not be used when running this command
# Proposed technical implementation details (optional)
In general we could have a keybind that maps to one key combination when pressed would disable all keybinds and when task is done we can come back

No files, tests, or entry points are named. Start by locating the terminal's keybinding handling and clarifying how a toggle should interact with applications such as Vim; done means one key combination suppresses all terminal keybindings while active and restores them afterward.
