Support for Navigate forward/back in the describe dialog

The pl/sql editor allows for navigating forward/back using alt left/right. Would like to see this functionality in the Describe Objects dialog.

I am no expert on the Editor, so maybe I’m missing something (our Editor guy is on vacation right now) - but I don’t see any navigation in the Editor for Alt+left/right.

I do see Alt+PgUp/PgDown to jump between the tabs, but the describe window supports that already.

Am I missing something?
