fix:Keyboard shortcuts not functioning as expected (Ctrl+C / Ctrl+V / Ctrl+Shift+C)

[Sumabhat11]

Describe the bug
Keyboard shortcuts are not behaving correctly:

• Ctrl + C and Ctrl + V should work for copy and paste operations.
• Ctrl + Shift + C should send a SIGINT signal.

Currently, these shortcuts are either not working or triggering unintended behavior.

To Reproduce
Steps to reproduce the behavior:

1. Open the terminal.
2. Try using Ctrl + C and Ctrl + V for copy/paste.
3. Try using Ctrl + Shift + C to send a SIGINT.
4. Observe that the expected behavior does not occur.

Expected behavior

• Ctrl + C → Copy
• Ctrl + V → Paste
• Ctrl + Shift + C → Send SIGINT

Additional context
The key mapping likely needs to be updated to properly differentiate between copy/paste and SIGINT.
