How can I set indent 2 in Aquamacs?

Question

The default indentation is 4 for tabs. How can I set it to 2 in Aquamacs? I see a configuration file .emacs.d in my home directory, but it doesn't look like the right file:

" ============================================================================
" Netrw Directory Listing                                        (netrw v140)
"   /Users/lucerne/.emacs.d
"   Sorted by      name
"   Sort sequence: [\/]$,\<core\%(\.\d\+\)\=\>,\.h$,\.c$,\.cpp$,*,\.o$,\.obj$,\.in
"   Quick Help: <F1>:help  -:go up dir  D:delete  R:rename  s:sort-by  x:exec
" ============================================================================
../                                                                               
~     

Answer 1

The customization option you are looking for might be: Top Level / Editing / Indent / Standard Indent

That is, Hit command comma or choose Options/Customize/Top-Level Customizations Click on Editing, then on Indent, then on Standard Indent Change the number to 2 Click on "Save for Future Sessions"

Have fun!
