Highlighting text with shift and arrow keys

### Describe the bug

I tried to highlight a text/word with to replace it or correct spelling mistakes.
Instead the cursor just moved to the left, if I quit copilot it works in the same terminal session.

### Affected version

0.0.421

### Steps to reproduce the behavior

1. Type a text in the copilot input field

2. Try to highlight the text with `Shift` + `Arrow Left` Key

But the cursor just moves to the left.
The case is the same if I also add the `Ctrl` key to try to highlight a whole word.

### Expected behavior

The text should be highlighted lik in the normal terminal.
