NAME

       font-size - interactive font size setter

USAGE

       Put the font-size script into $HOME/.urxvt/ext/ and add it to the list of enabled perl-extensions in
       ~/.Xresources:

         URxvt.perl-ext-common: ...,font-size

       The extension automatically binds Ctrl++ to the 'increase' function, Ctrl+- to 'decrease', and Ctrl+0 to
       'reset'. To use the other available functions or change the keys, add some keybindings of your own:

         URxvt.keysym.C-Up:     font-size:increase
         URxvt.keysym.C-Down:   font-size:decrease
         URxvt.keysym.C-S-Up:   font-size:incglobal
         URxvt.keysym.C-S-Down: font-size:decglobal
         URxvt.keysym.C-equal:  font-size:reset
         URxvt.keysym.C-slash:  font-size:show

       Note that for urxvt versions older than 9.21 the resources have to look like this:

         URxvt.keysym.C-Up:     perl:font-size:increase
         URxvt.keysym.C-Down:   perl:font-size:decrease
         URxvt.keysym.C-S-Up:   perl:font-size:incglobal
         URxvt.keysym.C-S-Down: perl:font-size:decglobal
         URxvt.keysym.C-equal:  perl:font-size:reset
         URxvt.keysym.C-slash:  perl:font-size:show

       Supported functions:

       • increase/decrease:

               increase or decrease the font size of the current terminal.

       • incglobal/decglobal:

               same as above and also adjust the X server values so all newly
               started terminals will use the same fontsize.

       • incsave/decsave:

               same as incglobal/decglobal and also modify the ~/.Xresources
               file so the changed font sizes will persist over a restart of
               the X server or a reboot.

       • reset:

               reset the font size to the value of the resource when starting
               the terminal.

       • show

               show the current value of the 'font' resource in a popup.

       You can also change the step size that the script will use to increase the font size:

         URxvt.font-size.step: 4

       The default step size is 1. This means that with this setting a size change sequence would be for example
       8->12->16->20  instead  of  8->9->10->11->12  etc.  Please note that many X11 fonts are only available in
       specific sizes, though, and odd sizes are often not available, resulting in an effective step size  of  2
       instead of 1 in that case.
