I am having trouble finding the shortcut for Zooming (increasing font size) / unZooming (decreasing font size) in emacs. I must add that I am interested in the command-line emacs (i.e. no window, i.e. "-nw" option) only, I don't use the graphical interface.
The Zoom-in command is supposed to be C-x C-+ and the Zoom-out C-x C--, also since I am using a laptop - often without mouse -, I am not interested by a "mouse-wheel up/down" option.
I tried C-x C-+ in two ways:
"typing Ctrl then 'x' then Ctrl then key '1' which is the key with the '+' symbol above the 1 on my qwertz keyboard"
"typing Ctrl then 'x' then Ctrl - WHILE HOLDING SHIFT" then key '1' which is the key with the '+' symbol above the 1 on my qwertz
keyboard"
neither seem to work, although the second would seem to make more sense, i.e. to hold shift as if to write the '+' sign that i can get with shift-'1'
So I wonder: is the shortcut C-x C-+ only intended for people equipped with a numeric keypad ? or is there another way and in any case what do you suggest ?
And no, this question (How do I bind C-= in emacs?) does not answer mine, in fact I don't even understand what it is about (question is totally unclear and unrelated to mine - as far as i understand)...
I am just asking how to Zoom/unZoom i.e. increase/decrease font size...
Since emacs is running within a terminal, you can't directly control the font as you would running as a GUI app. To zoom in and out, you need to use the method that your terminal application provides for changing the font size. This is often <ctrl>+ and <ctrl>-, but your terminal keybindings may be different.
