Clear screen option like macOS and Gnome terminals

[ascarter]

Description of the new feature/enhancement

Add an option (or options) to clear the screen/buffer. As a long time macOS and Linux user, I instinctively hit Cmd+K to clear the buffer (of course Ctrl-K on windows). It would be very useful to offer some clearing options like the macOS terminal does (clear to start, clear screen, clear scrollback, clear to mark). Gnome terminal also has some similar options. Ideally should be able to be mapped to a shortcut (ideally Ctrl+k or Ctrl+shift+k) but a menu option is good as well (like settings).

Proposed technical implementation details (optional)

clear already works for PowerShell, cmd, and bash. I believe this is a standard escape sequence for VT100 terminals. Ideally, just let this be a way to issue that escape sequence to the terminal that is running.

• Expose one or more clear screen options that can be associated to a shortcut key
• Either map Ctrl+k, Ctrl+Shift+k to clear screen by default or offer documentation so a user can add to the profile
