How to scroll using keyboard in 'Custom patch' panel?

[pm-gmr]

When I'm creating a patch from an existing commit, I can't change the focus to "Custom patch" panel to scroll it up/down. The only way to scroll it is using mouse wheel. Is there a way to do that using keyboard? PgUp and PgDown only scroll the Patch panel i.e. the panel where I create the custom patch from.

It would be great if I could use Tab key to switch to that panel and scroll just like we do when staging/unstaging changes.

Unfortunately that's not yet possible, an issue was created a while ago. Contributions are welcome, though!
