kitten-@-set-font-size - Man Page

Set the font size in the active top-level OS window


kitten @ set-font-size FONT_SIZE


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


--all,  -a

By default, the font size is only changed in the active OS window, this option will cause it to be changed in all OS windows. It also changes the font size for any newly created OS Windows in the future.

The name of an environment variable to read the password from. Used if no --password-file is supplied. Defaults to checking the environment variable KITTY_RC_PASSWORD.
