Customize tree node expand/collapse keyboard shortcut?

[FlagTech]

Pressing Enter while a node is focused in the Data Explorer pane expands/collapses a node. I prefer Spacebar for this but don't see that the expand/collapse key is customizable in the Customize dialog.

If I'm missing where this can be customized, please tell me. If not, please put it on the wishlist.

Thanks.

[Edit - admin: I moved it here since that capability does not currently exist. A workaround for this is to use a macro tool such as AutoHotkey]
