I started using Emacs a while back and can’t believe how I worked without it in gedit. One can customise Emacs anyway one likes. Here is my .emacs file which enables gtags mode for C files, indentation for C source files, named sessions saving/naming, automatic brace pairings, maximise on opening emacs and changing frames with shift and arrow keys. Do note that nothing in the below .emacs file is my work, it has all been collected from different places on the internet.
