If you think you can benefit by others' mistakes you may find some notes
& practical advice re: typing numbers is this famous Q&A:

http://www.diniwed.net/typing.html

I concur that prefixing Vim normal mode commands with a count, such as
'7dw' to delete the next seven words is ineffective.. Something like
'dw....' where you delete the next word (dw) and repeat the last command
(.) a number of times is the way I normally do it because I don't have
to count the words before I even start deleting. While I hit the dot (.)
repeatedly, I can see what I'm deleting and I know when to stop.. And
I can always hit 'u' for undo to bring back the words I deleted one at
a time in the event I got carried away.

Come to think of it, the only pratical use I have for counts is when
I need something like a line of dashes:

i - <Esc> x 80p

IOW - i for insert mode, one dash, <Esc> back to normal mode, 'x' to
delete the dash and yank it to the unnamed register, and finally 80p to
create a line of eighty dashes..

Another possibility that comes to mind might be to convert your files to
UTF-16.. which I believe is the Windows way of doing unicode.

I haven't seriously looked into it, but if you stick with UTF-8, could
your initial problem be addressed by creating a mapping that sets the
value of 'encoding' to match 'fenc', issues the ga command, and resets
'encoding' to utf8 immediately afterwards?

I may be wrong about this, and I can't say I understand the
implications, but the root cause of the problem here would appear to be
that contrary to 'fenc', 'encoding' is one of those options that cannot
be set locally - if you do a ':setl enc=latin1' and switch to another
buffer, a ':set enc?' reveals that the encoding has been globally
changed to 'latin1'. I'm sure there must be very good reasons for this
behavior. The above sequence is obviously not exactly 'atomic' but
I don't see it messing up anything.

Thanks for the clarification.

I ran into similar problems when I reviewed an APL derivate called A+
that does not support any form of unicode and has its own peculiar
extended ASCII code page. I had to say good-bye to my funky unicode
listchars, tabline.. etc. and use a different .vimrc.. not wanting to
mess up the original one with a bunch of conditionals..

Not being a Windows user, I cannot think of anything practical..

You may find additional ideas by reading this document I came across
a few days ago:

What about some of the options in another current discussion?

The only catch is that (depending on your encoding and other
stellar alignments) some alt+letter combinations produce various
accented & ASCII characters >128. If you type those characters
intentionally (which it sounds like you don't), it may interfere.
Otherwise, they should be safe to use (as mentioned in a
sibling reply, they're case-sensitive).

Yeah. I see several problems that I don't know how to fix.

The first is, the function has to load each line and add them to a
string. I haven't found a way of just slurping the entire file in.

The second is, the code has to be reparsed on every update.

Finally, it has to do this *every* time the statusline is updated,
whether or not the buffer has been changed.

So, I need to figure out how to:

o load the contents of the file faster
o how to have a variable for each buffer so it doesn't need to be
reloaded all the time
o figure out how often to actually rescan and reparse the file

Alt keys do nothing special in Vim by default. If you're using GUI Vim
you may need to read :help 'winaltkeys' but it sounds like you're
sticking with the terminal.

You can probably map it directly:

:inoremap <A-i> <Esc>

or

:inoremap <M-i> <Esc>

Note that Alt maps, unlike CTRL maps, are case-sensitive.

To enable syntax highlight and such, you will need to create a .vimrc.
This is highly recommended anyway. There is a reasonable example that
ships with Vim.

Specifically, you will need these lines in your .vimrc file:

filetype plugin indent on
syntax on

Take a look at:

(within Vim): :help usr_05

This depends on the platform you will be developing on. gcc is pretty
good and I think it comes standard on most *nix platforms these days.
MinGW provides the same compiler for Windows.
