Re: Changing font size of all the buffers including the status line and the characters shown in electric-buffer

[ISHIKAWA,chiaki]

Thank you all the help posted to this mailing list.

After looking at the tips posted so far, I tested the one posted by Van L.:

M-x customize-group RET faces RET

Basic Faces
  Default
    Height

I did not realize the change to this is propagated to Japanese fonts as well as 
dired mode font faces (which I presume are used electric-dired mode). Sure the 
characters in modeline also becomes large, too.

So, although I rarely use customization feature of emacs, this time I am a 
happy user of this.
For those who are unfamiliar with customization (maybe I am in the minority?),
here is how you change the height.
After M-x customize-group RET faces RET You click on the Basic Faces line using 
mouse, and then
using [Tab] to move to the Default font entry.
Then hit RET/ENTER, a set of editable entries will appear.
In my case, the height section contains size (in 1/10 pt) and it was 101.
I rewrote it to 202 and from the [STATUS] button, saved the value for future 
sessions (as well as for the current session).

Voila the character size including the modeline, the buffers (Japanese 
characters and ASCII English characters both are affected), and electric-dired 
mode all became twice as large and I am a happy user now.

I will study the other tips/hints and see how they compare to the solution 
above.

Thank you, everybody!


Happy Hacking (in the good old sense of the phrase).
