text-scale-mode

text-scale-mode is an interactive compiled Lisp function in `face-remap.el'.


(text-scale-mode &optional ARG)

Minor mode for displaying buffer text in a larger/smaller font.
With a prefix argument ARG, enable the mode if ARG is positive,
and disable it otherwise. If called from Lisp, enable the mode
if ARG is omitted or nil.

The amount of scaling is determined by the variable
`text-scale-mode-amount': one step scales the global default
face size by the value of the variable `text-scale-mode-step'
(a negative amount shrinks the text).

The `text-scale-increase', `text-scale-decrease', and
`text-scale-set' functions may be used to interactively modify
the variable `text-scale-mode-amount' (they also enable or
disable `text-scale-mode' as necessary).
