certainly not directly. the ctl-alt-+/- key binding is direct to the X
server itself. it completely bypasses all widget toolkits and the
window manager. it generally results in a reset of the video
interface, amongst other things. not the sort of stuff an application
would tend to do ;)

there is no "font size of the desktop". individual applications use
various font sizes, and offer their users various ways of controlling
those sizes.
