From MediaWiki.org:

I would like to have an omnibar in VE. This is a single text field where
a user can search for things they want to do, instead of clicking a
button you can invoke omnibar with a keyboard shortcut and then search
for the task you want to do. This would be helpful to easier access those
buttons which don't have shortcuts now. Like managing category, inserting
reference, changing to source editor etc.

Seems like it could be a lot of work to implement – for example, internationalisation of such controls might be hard – but it might be particularly useful for power users (or for controls that don't have a keyboard shortcut, as the proposer notes).
