Keyboard Forwarding

How do you configure CoreShell to pass keyboard commands through correctly?

For example, connected to a linux server and using Journalctl, I need to be able to sent SHFT + PG UP to scroll past pages of logs instead of UP or DOWN a line at the time.

If I try this right now Core Shell detects its own keyboard shortcuts and scrolls the terminal window up and down.

May I ask how do you achieve this in system Terminal app? Thanks.
