I'm using Ubuntu 17.10 with GNOME 3. How can I show all open windows of a certain application using the sidebar (aka Ubuntu Dock)? Right now I have to right-click and select "all windows" to see my other open windows.

Is there a quicker way to do this?

    I guess what you are looking for is done by Super + W under Ubuntu 16.04 with Unity. It provides you with a tile-style view of all open windows. As you are using Ubuntu 17.10 with the Unity-like Gnome environment, the key might be different. Under Gnome you may as well just pres Super to get a tile-like view of all open applications. BTW: Super = Windows Key

I am not aware of any window-preview-on-mouse-hover feature, but you can activate previews of open windows on

  • Primary mouse button click by running

    gsettings set org.gnome.shell.extensions.dash-to-dock click-action 'previews'
  • shift+click by running

    gsettings set org.gnome.shell.extensions.dash-to-dock shift-click-action 'previews'
  • Middle mouse button click by running

    gsettings set org.gnome.shell.extensions.dash-to-dock middle-click-action 'previews'
  • shift+middle mouse button click by running

    gsettings set org.gnome.shell.extensions.dash-to-dock shift-middle-click-action 'previews'

(To find out all possible options for an action, run

gsettings range org.gnome.shell.extensions.dash-to-dock click-action

and so.)

As a side note, a GNOME extension called Dash to Panel puts the application icons to the top bar (and provides an option to move top bar to bottom):

It also provides the window-preview-on-mouse-hover feature:

    I'm not sure if I should accept this as an answer as it isn't exactly what I asked? But this works just as well!

    @James If I'm not mistaken the preview-on-hover feature you're looking for is not yet implemented. But I would recommend not accepting the answer so that in future if/when the feature is implemented others will be more motivated to post a new answer.

    @James Dash to Panel provides preview-on-hover, see edit to my answer.

    The first one is what most people are looking for. If you want to revert back, replace previews with focus-or-previews

For Ubuntu 20.04

gsettings set org.gnome.shell.extensions.dash-to-dock click-action minimize-or-previews

Not your exact problem but did you try Dash to Dock ?


If you click on Behaviour you can select Show Window Previews when you click on an app in the dock, if you have two instances of the same app a preview of both will appear (instead of having to right click on an app)
