Hi,
I experience unusual behavior of spacebar in specific applications. When I open a folder in an application using Ctrl+O (or open folder icon), open search bar using Ctrl+F and type the file name, pressing space bar automatically selects the file that has the search word in the file. For example, if the folder has files "test file 1", "test file 2" and "test file 3", typing "test" in the search bar and hitting the spacebar automatically selects "test file 1". So, I am unable to select and open either "test file 2" or "test file 3". A short video showing this behavior is given below

This behavior is observed in the following applications in my computer
Libreoffice 6.3
Evince
Gnumeric
Zim wiki
Abiword

One thing (I think) is common among the applications is they are GNOME/GTK based. I do not see this behavior in KDE applications. The keyboard navigation for GNOME lists SPACEBAR as "Activate a focused item such as a button, check box, or list item." (https://help.ubuntu.com/stable/ubuntu-h ... av.html.en). Is there a way to disable this "SPACE: Activate a focused item such as a button, check box, or list item." feature in KDE ? If not, how do I enter a space in search bar of GNOME/GTK applications in KDE environment ? Your help in resolving this issue is greatly appreciated.
