Can vim zoom-in and zoom-out?
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++)
The font size of a a console-based vim is determined by the font size of the terminal. So changing the vim font size can be achieved by changing font size of the terminal that vim is called from :
|Terminal emulators | + font size |- font size
--------------------------------------------------------------------
| xterm |Shift + Keypad Plus(+)|Shift + Keypad Minus(-)
| |Or control + mouse right click to choose the
| |desired font size.
--------------------------------------------------------------------
| GNOME terminal |Control+Shift+Plus(+) |Control + Minus(-)
| |Do not use keypad. |Do not use keypad.
--------------------------------------------------------------------
| Terminator |Control+Shift+Plus(+) |Control+Minus(-)
| |Do not use keypad. |Do not use keypad.
--------------------------------------------------------------------
| Konsole |Control+Mouse Wheel |Control + Mouse Wheel
| |Scroll Up, or |Scroll Down, or
| |Control + Plus(+) |Control + Minus(-)
--------------------------------------------------------------------
| lilyterm | Control + Plus(+) |Control + Minus(-)
--------------------------------------------------------------------
| xfce4-terminal | Right Click/Preferences/Appearance.
