I would particularly want to use it with the 'c' command.
[cut]
I'm using c quite often. I wouldn't remap it ;)
I think the OP wants an (in vim nomenclature) "operator pending
mode mapping", so that it can be used *with* the "c" command,
rather than *instead* of the "c" command.
:onoremap > /\u<cr>
:onoremap <lt> ?\u<cr>
This pair of mappings will allow one to do
c>
or
c<
to change to the next/previous start of a "camel-case word"
The 2nd mapping has problems if you're in the first "word" or on
the 1st character of the 2nd word (e.g. "abcdEfgHiJklmno" and
your cursor is on the "E"), so you can change the mapping to
:onoremap <lt> ?\u<bslash><bar><bslash><lt><cr>
which will handle both cases.
There's a good bit of help on the matter scattered throughout the
docs. Some suggested places to start reading:
:help omap
:help operator-pending
:help map_backslash
:help <bar>
(reading the surrounding section on bslash, lt, cr and when to
use them too is helpful)
These mappings do happen to break the convenience of the ">>" and
"<<" commands, as after the first "<" or ">", vim is now in
operator-pending mode, so unless there is another uppercase
letter on the line (before or after the cursor respectively),
this will give you grief. However, you can map them to other
keys if you prefer (plus/minus are rarely used, given their
synonymity with j/k), or you might be able to create additional
mappings for ">>" and "<<" to explicitly perform their original
actions:
:nnoremap <lt><lt> <lt><lt>
:nnoremap >> >>
might do the trick (untested).
