accessibilitygnome-shellkeyboardshortcut-keys
On Ubuntu 16.04 LTS I have used simple keyboard shortcut to set property Always on Top (Nautilus window as example):
Alt+Space,
t
After next Alt+Space or right mouse click I see that window was set to Always on Top.
In standard Ubuntu 18.04 LTS with GNOME Shell I can press Alt+Space:
but it does not react to t.
Seems to be a real bug 1710421 since 17.10.
How to enable such menu accelerators/mnemonics in standard Ubuntu 18.04 LTS?
I find that is easy to remap the GNOME shortcut to achieve the same thing, but mapping 3 keys is unsupported of you use the space key, it appears, so there are two options that I know:
The first is remapping the close window command; currently in “Ctrl + Q” or “Alt + F4” to “ Alt + C”. You can do this by going to Settings -> Devices -> Keyboard and then scrolling to the Close window command, then remapping the command, then again, you can only type two keys. Do the same to maximize window, to “Alt + X”
There's an simple workaround here:
In case you don't need to switch between keyboard layouts, you can get some shortcuts working again if you use the "Tweaks" tool for Gnome.
sudo apt install gnome-tweak-toolThen
- Open "Tweaks"
- Select the tab "Keyboard & Mouse"
- Click "Additional Layout Options"
- Disable entries in the "Switching to another layout" dialog
In my case this gave me back the "ALT + SHIFT" combinations which are essential in the Eclipse IDE for refactoring.
It works beautifully!

On GNOME Shell it is impossible! Welcome to the new brave world with unpredictable limits and problems!
To get these shortcuts on Ubuntu 18.04 LTS and 20.04 LTS in place you can switch to:
Unity - installable with
sudo apt-get install ubuntu-unity-desktop:GNOME FlashBack - installable with
sudo apt-get install gnome-panel:MATE Desktop Environment (my favorite, as it avoids GNOMEs Hell) - installable with
sudo apt-get install ubuntu-mate-desktop^:XFCE (
xubuntu-desktop^) does not have mnemonic for Always on Top, but usable and looks very nice:Cinnamon (
cinnamon-desktop-environment) have all necessary mnemonics:KDE (
kubuntu-desktop^) have mnemonics, they may be accessed from Alt+F3 (so called Window Operations Menu) - for example to keep window above others you need to click Alt+F3, M (for More Actions), A (for Keep Above Others) and menu is rich:Openbox (
openbox), LXDE / LXQT / Lubuntu (lubuntu-desktop^,lxqt) have mnemonics, they are accessed with Alt+Space:Budgie (
ubuntu-budgie-desktop^) have mnemonics, they are accessed with Alt+Space:
