I have hit a few CTRL- in command line and I see the text in the terminal getting smaller with every invocation.  What is going on here and is there a way to redo ie magnify the text to bring it back to the original size via a command?Edit: As per Christopher's suggestion in the comment I can get back to my original font size by hitting CTRL+ but I would still like to understand what is going on behind the scenes here.
Why does hitting Ctrl minus in the command line shrink the font size?
terminal;keyboard shortcuts;gnome terminal
It's a somewhat standard keyboard shortcut (it works in Konsole, too).It's simply bound to reduce font size (and simmetrically, Ctrl+ to increase font size).You can easily disable/modify by going to the shortcuts preferences.
