don*t know wether you've heard/read about those UI components called Palletes.
I think they are a very nice improvment for the keyboard afficionados. They let you very quickly get the target out of huge haystack.
Short description
UI-wise,basically they're nothing more than borderless-popups without any buttons performing different kind of real-time searches with the result list shown below for quick selection (and selection by <enter>).
In my dreams, for XY I would like to have one for
- all commands (fuzzy search just like the Jump in the configuration), on selection+<enter> the command is run
- all (multiline) scripts (files) below <xyscript> (fuzzy name search), on selection+<enter> the script is run (maybe opened with <modifier>-<enter>).
Example for Atom editor
