(This bug applies not only to Dolphin but to Kate, Kmail, Gwenview, and every other program that appears to use KHamburgerMenu. There is no bugs category for KHamburgerMenu, so I'm posting here, excuse me in advance.)
There is no way to discover that Ctrl-Alt-I brings up the excellent command search HUD box.
The keyboard shortcut cannot even be discovered in System Settings -> Shortcuts after intently looking for 5 minutes.
STEPS TO REPRODUCE
1. Look in all menus of Dolphin (or Kate, or Kmail...) to see if there is a mention of how to discover and invoke the command search HUD via Ctrl-Alt-I.
There is no menu item entry in any menu that would help others to find this useful feature. There is no way to know other than to be in-the-know.
In the Help menu, have a menu item that says something like:
Quick search all commands Ctrl-Alt-I
Operating System: KDE neon 5.22
KDE Plasma Version: 5.22.5
KDE Frameworks Version: 5.85.0
Qt Version: 5.15.3
Kernel Version: 5.11.0-27-generic (64-bit)
Graphics Platform: X11
KHamburgerMenu likes in KConfigWidgets, but this feature is not specific to KHamburgerMenu. Probably we need an item added to the general help menu which I think lives in KXMLGui?
I totally agree with what this bug report wishes for.
>this feature is not specific to KHamburgerMenu
I agree. This should have no relation to KHamburgerMenu code-wise. The hamburger menu only displays the Help menu from the menu bar.
>Probably we need an item added to the general help menu which I think lives in KXMLGui?
I think so too. I think it is likely that this can be fully implemented without touching anything outside of the KXmlGui framework.

Awesome! Thank you Waqar Ahmed 🙏
