You still haven't corrected this i (should be a). Using <esc>A is
much shorter anyway :-) Thus just use:
> imap <C-S-Right> <Esc>A
On linux you can do something like
xmodmap -e 'clear Lock' -e 'keycode 0x42 = Escape'
to map capslock to <esc>. Then typing <caps>b is even more convinient
than using the default ctrl-left and ctrl-right combos. Your <esc>
mapping stuff won't work with visual mode. So do yourself a favour,
read :h motion once to see what mappings are availible. Repeat this once
a month till you feel you know most mappings you really need. You'll
find mappings such as tT fF (and using ; and , (repeat last movement)
which are much better than ctrl- quirks. And you'll be able to use them
in visual mode as well.
You'll be more precise with vim mappings as well. Example:
Lookup the difference e E w W. Which behaviour do you want for c-right?
I know its hard to learn something you're not used to. Put it will pay off soon
if you spend some time within vim.
At least this is what I would do.. But it depends on how much time
you'll spend coding or editing text in your life.
my 2 cents again :-)
