6" To use it, copy it to
7"     for Unix and OS/2:  ~/.vimrc
8"	      for Amiga:  s:.vimrc
9"  for MS-DOS and Win32:  $VIM\_vimrc
10"	    for OpenVMS:  sys$login:.vimrc
11
12" When started as "evim", evim.vim will already have done these settings.
13if v:progname =~? "evim"
14  finish
15endif
16
17" Use Vim settings, rather than Vi settings (much better!).
18" This must be first, because it changes other options as a side effect.

21" allow backspacing over everything in insert mode
22set backspace=indent,eol,start

29set history=50		" keep 50 lines of command line history
30set ruler		" show the cursor position all the time
31set showcmd		" display incomplete commands
32set incsearch		" do incremental searching
33
34" For Win32 GUI: remove 't' flag from 'guioptions': no tearoff menu entries
35" let &guioptions = substitute(&guioptions, "t", "", "g")
36
37" Don't use Ex mode, use Q for formatting
38map Q gq
39
40" CTRL-U in insert mode deletes a lot.  Use CTRL-G u to first break undo,
41" so that you can undo CTRL-U after inserting a line break.
42inoremap <C-U> <C-G>u<C-U>

44" In many terminal emulators the mouse works just fine, thus enable it.
45if has('mouse')

47endif
48
49" Switch syntax highlighting on, when the terminal has colors
50" Also switch on highlighting the last used search pattern.

73  " Don't do it when the position is invalid or when inside an event handler
74  " (happens when dropping a file on gvim).
75  " Also don't do it when the mark is in the first line, that is the default
76  " position when opening a file.

91" file it was loaded from, thus the changes you made.
