Is there a better way to zoom in?
xzoom is a good screen magnifier for X, with a separate draggable window. To use, you drag it's window portion over what you want to zoom in on.
To install, run the command in terminal:
sudo apt install xzoom
To run, either type xzoom in terminal or type "xz" or "magnifier" in the power key search bar (application launcher). It doesn't come up when typing "zoom". Click and hold left click on the xzoom window and drag to what you want to magnify. Move xzoom to where you want it, and resize it as you wish.
I am using Ubuntu 19.04.
