After clicking Show Applications in the dock, on the occasion I don't click an app, I'd like to click anywhere in the window to close it. Currently I have to mouse down and click the Show Application icon again for the window to close. Is this possible?
There is a GNOME shell extension which does the job to some extent: Hide Overview When Click Overview.
A Click on an empty space in the overview hide the overview. If you clicked at workspacesPage it minimizes all windows on the current workspace and show desktop. Other pages just hide overview.
But I prefer pressing Super to close the 'Show Applications' screen quickly.
As a workaround you can create a launcher for simulating Escape key.
For simulating you need xdotool to be installed.
sudo apt install xdotool
Create a ESC.desktop file in ~/.local/share/applications/
gedit ~/.local/share/applications/ESC.desktop
Paste the below content in it.
[Desktop Entry]
Version=1.0
Terminal=false
Type=Application
Name=ESC
Exec=xdotool key Escape
Name[en_IN]=ESC
Save & Close.
Run
chmod +x ~/.local/share/applications/ESC.desktop
to make the file executable.
Now when you click show all apps icon, you will have "ESC" entry.
