I would like to know what are the possible ways of using an unity-like HUD (Heads Up Display) on Ubuntu 18.04, preferably with the gnome shell as default.
by HUD I mean the access and search of menu items (not applications or files!) when pressing (and releasing) alt.
Are there usable gnome extension or third-party apps that works in 18.04?
There are already some discussion here. But this is less specific, as I am searching for an Ubuntu 18.04 (with Gnome shell) solution.
some of the solutions indicated are:
plotinus seems promising, but only works with GTK+ apps.
Gnome Global Application Menu(HUD for Gnome), comments say it doesn't work in 18.04, although the last comment (from 06.05.18) says the latest version if installed manually from github should work in 18.04. (I would appreciate a detailed instruction of how to install an extension manually)
