Changing font size in urxvt

I finally had the need to dynamically change my font size in urxvt. If you search you will find keybindings to do this, such as the ones recommended in this thread . With my teeny planck keyboard, i3 , and tmux I don't really have room in my head for learning other keybindings.

In that thread there is also a printf command that changes the font size via a terminal escape code.

alias biggest="printf '\33]50;%s\007' \"xft:Source Code Pro:pixelsize=30\""
alias big="printf '\33]50;%s\007' \"xft:Source Code Pro:pixelsize=20\""
alias small="printf '\33]50;%s\007' \"xft:Source Code Pro:pixelsize=10\""
alias teeny="printf '\33]50;%s\007' \"xft:Source Code Pro:pixelsize=8\""
alias normal="printf '\33]50;%s\007' \"xft:Source Code Pro:pixelsize=12\""

I added the above aliases to my zshrc .
