Clipboard hotkeys

[JcBernack]

Adding hotkeys to copy responses to the clipboard would be very useful.
Ideally with the same hotkeys people are already used to, e.g. from ChatGPT:

• Ctrl + Shift + C Copy last response to clipboard
• Ctrl + Shift + ; Copy last code block to clipboard

Getting this to work cross-platform should be fairly simple using something like pyperclip

import pyperclip
pyperclip.copy('The text to be copied to the clipboard.')
