I am a loyal Linux fan who has been spending a lot of time using iTerm on a mac lately.  One thing I really like about the mac, and iTerm in particular, is the ability to use a keyboard shortcut to in/decrease the font size.  I believe it's apple+ and apple- to do this. AFAIK this is also possible using gnome-terminal and possibly konqueror.However, I am an rxvt-unicode user.  Period.  I'm not willing to switch my terminal, but I would like to be able to have the ability to quickly resize the font.  Currently, to resize the font I have to do this:Detach tmux$EDITOR ~/.Xdefaultsxrdb -all ~/.Xdefaultsclose terminalopen a new terminalReattach tmuxI'm thinking that it must be possible to script something that would reduce the above steps to one by perhaps binding to a keyboard shortcut, maybe with xbindkeys or something similar.  Anyone have any thoughts on how this might best be accomplished?Note:  I'm using awesome window manager and prefer to keep things ultra-simple (i.e., no Gnome/KDE-specific solutions, please).@Keith: I am familiar with the escape sequences and it's my fault for not saying so explicitly in my original question, but:  I'm looking for a solution that will persist between sessions.  Likely that will involve writing some code.
Increase font size in rxvt-unicode without editing ~/.Xdefaults
fonts;rxvt
I'm answering my own question (with code!) and upvoting Keith for his keysym suggestion.  However, Keith's solution does not persist the resized font to the Xresources file, so that the resize is available when the next window is opened, whereas mine does:https://github.com/noah/urxvt-font
