In previous versions of ptyxis, Ctrl-= would zoom in text, without
having to hold shift. This is the default in most applications (e.g.
browsers, gnome-terminal). In the current version (I don't know exactly
when this changed), it seems to only accept the version that requires
pressing both control and shift.

I was able to fix this by changing the keyboard shortcuts, but I'd like
to suggest changing the default, for usability.
