kitten-@-set-font-size - Set the font size in the active top-level OS window

       Sets  the  font  size  to  the  specified size, in pts. Note that in kitty all sub-windows in the same OS
       window must have the same font size. A value of zero resets the font size to default. Prefixing the value
       with a + or - increments the font size by the specified amount. Use -- before using  -  to  have  it  not
       mistaken for a option. For example: kitten @ set-font-size -- -2

--to   An address for the kitty instance to control. Corresponds  to  the  address  given  to  the  kitty
              instance  via the --listen-onoptionorthelisten_onsettinginkitty.conf.Ifnotspecified,theenvironmentvariableKITTY_LISTEN_ONischecked.Ifthatisalsonotfound,messagesaresenttothecontrollingterminalforthisprocess,i.e.theywillonlyworkifthisprocessisrunwithinakittywindow.--password
              A password to use when contacting kitty. This will cause kitty to ask the user for  permission  to
              perform the specified action, unless the password has been accepted before or is pre-configured in
              kitty.conf.Touseablankpasswordspecify--use-passwordasalways.--password-file[=rc-pass]
              A  file  from  which  to  read  the  password.  Trailing whitespace is ignored. Relative paths are
              resolved from the kitty configuration directory. Use - to read from STDIN. Use fd:num to read from
              the file descriptor num. Used if no --passwordissupplied.Defaultstocheckingfortherc-passfileinthekittyconfigurationdirectory.--password-env[=KITTY_RC_PASSWORD]
              The  name  of  an  environment  variable  to read the password from. Used if no --password-fileissupplied.DefaultstocheckingtheenvironmentvariableKITTY_RC_PASSWORD.--use-password[=if-available]
              If no password is available, kitty will usually just send the remote  control  command  without  a
              password. This option can be used to force it to always or never use the supplied password. If set
              to always and no password is provided, the blank password is used.

              Choices: if-available, always, never
