How do I prevent the font from changing size when I use left Alt + mouse left click to then select a few lines to enter the same input. I think it's called column mode or something. Every time I do this, the font is reduced and drives me nuts since I end up at a different line and then must try to remember where I was before.
So is there a setting I can change that will prevent the font size from changing when I use this mode?

Thanks in advance.

Thanks mate, you are a life saver. That was so simple. I went through all options for nothing.
Have a great weekend!
