In Ubuntu 18.10, the shortcut for showing applications is Super+A. Is there any possibility to assign Super alone for that? I tried from the settings-keyboard shortcuts, but it asks for a combination of Super+some-other-key.

Update
The original answer relies on xcape or ksuperkey, tools that work on Xorg only. Users on more recent versions of Ubuntu (Gnome Shell 40 and up) can use the extension Start Overlay in Application View by Hex_cz to have Super show applications rather than the overview.
(Previous answer) Xorg only
You can do so by reassigning releasing the Super key alone to a specific shortcut. For this, you need an additional little tool such as xcape(available by default in the Ubuntu repositories) or ksuperkey.
First, disable the existing binding of Super:
gsettings set org.gnome.mutter overlay-key ''Then, have the tool to redirect pressing and releasing Super autostart during login with the following command:
xcape -e "Super_L=Super_L|a"As Super+a triggers the application overview, this command will trigger that binding if you press and release Super.

This does not work in Ubuntu 22.10. Not sure if it worked for any other versions after 18.10 either. Commented Nov 13, 2022 at 11:10

@Sнаđошƒаӽ indeed
xcapeandksuperkeyonly work on Xorg. On 22.04 and up, Wayland has become the default.– vanadiumCommented Nov 20, 2022 at 11:53 -
