Unable to change font size

[matlzztt]

Changing the # font_size variable wields no difference when I save kitty.conf. I've tried saving the file and restarting kitty. No avail.

Inputing Ctrl+Shift+F6 wielded this:

Failed to launch child: less
With error: No such file or directory
Press Enter or Esc to exit

OBS: I am, of course, able to change font size by Ctrl Shift + or Ctrl Shift -. My only point here is that changing the value in the config file seems to give me no effects whatsoever.

In case this is of any help, these are my current configs:

Remove the leading # to uncomment the setting before changing it.

You're supposed to remove the hashtag AND the space. Or, at the very least, that did it for me. Thank you very much!
