Can Vim zoom in and zoom out?
vim
Solution
You can use the methods detailed here: http://vim.wikia.com/wiki/Change_font_size_quickly to create keybindings to do this for you. (Though I'm surprised gvim doesn't support this out of the box, MacVim does with CMD++)
Problem
I found we can do that in Emacs: emacs zoom in/zoom out What is the equivalent in Vim?
