Suppose I'm a clueless user who wants to change the font I'm using. I've failed to find the right place to do this (which is the Format | Character...) dialog, so I go to Help | Search Commands. Well, I type "font", and what do I get? Insert / Insert Fontwork... Format Text / Outline / Font Effect Not what I was expecting! One of the main reasons for searching for a command is that its menu item phrasing is not intuitive for someone. I would expect the search to go further, and search some longer description of the command, and/or the text of the dialog the command opens, and/or help text for the command. More specifically, searching for "font" should definitely yield "Format | Character..." IMHO.

I support the idea to search not only in the "Label" property of a command but also in context, popup and in particular the tooltip labels. However, this wouldn't return .uno:FontDialog since it has no tooltip assigned, yet. If the idea goes beyond that and you imagine some maintained list of keyword - command association I don't think this is going to fly.

Ideally, there should be a collection of localizable "keywords" for every UNO (and other kind of) command displayable there; help topics should also appear there; as well as user macros. A sample of "blinking" was suggested in a comment mentioned above; indeed, today that feature is removed from the UI, so irrelevant, but other similar features are available all over the place, that exist as *part* of an UNO command, but do not appear in either UNO name, nor in its title/tooltip.
Wonder if the search for command function deserves an own META ticket.
