Topic: X terminal emulator with ScrollLock scrolling?

I want a X terminal emulator I can scroll with scroll lock, similar to syscons (Press scroll lock to freeze, and use arrows, pageup, pagedown to scroll).

Some time ago I tried to find a X terminal which could do this, but all of them seem to use shift+pageup ...

Does anyone know of a X terminal that can do this?

Trust me, I know what I'm doing.
