If you want to move through a camel case word, like CamelCaseWordWeWantToMoveThrough, word by word (eg from the 'C' on Camel to the 'C' on Case to the 'W' in word), you can add the following maps to assign Ctrl-right and Ctrl-left to do the job

This tip is pretty handy, but I just wish it would work in select mode so you could get the behavior common in Windows code editors when you do ctrl+shift+&lt;left&gt;or&lt;right&gt;. Any tips out there for this?

Tip: #1016 - Moving through camel case words

Created: October 10, 2005 Complexity: basic Author: Anthony Van Ham, Gerald Lai Version: 6.0 Karma: 14/11 Imported from: Tip#1016

Some programs use CamelCaseWords (or camelCaseWords). The following maps allow you to move word by word, for example, from the 'C' of Camel, to the 'C' of Case, to the 'W' of Words. 

imap <C-Right> ?:call search('\<\<Bar>\u', 'W')<CR>
imap <C-Left> ?:call search('\<\<Bar>\u', 'Wb')<CR>
map <C-Right> :call search('\<\<Bar>\u', 'W')<CR>
map <C-Left> :call search('\<\<Bar>\u', 'Wb')<CR>

Comments

Here is a more thorough version. It does not go through a CAPITALIZED word one character at a time. 

nnoremap <silent><C-Left> :<C-u>cal search('\<\<Bar>\U\@<=\u\<Bar>\u\ze\%(\U\&\>\@!\)\<Bar>\%^','bW')<CR>

nnoremap <silent><C-Right> :<C-u>cal search('\<\<Bar>\U\@<=\u\<Bar>\u\ze\%(\U\&\>\@!\)\<Bar>\%$','W')<CR>

inoremap <silent><C-Left> <C-o>:cal search('\<\<Bar>\U\@<=\u\<Bar>\u\ze\%(\U\&\>\@!\)\<Bar>\%^','bW')<CR>

inoremap <silent><C-Right> <C-o>:cal search('\<\<Bar>\U\@<=\u\<Bar>\u\ze\%(\U\&\>\@!\)\<Bar>\%$','W')<CR>

Enhanced version, originally in tip 1187

With the following, the cursor will stop at:

  1. The beginning of a word.
  2. The beginning of a run of camel characters.
  3. A camel character followed by a run of non-camel characters.
  4. The start of the file.
  5. The end of the file.
"Use one of the following to define the camel characters.
"Stop on capital letters.
:let g:camelchar = "A-Z"
"Also stop on numbers.
:let g:camelchar = "A-Z0-9"
"Include '.' for class member, ',' for separator, ';' end-statement,
"and <[< bracket starts and "'` quotes.
:let g:camelchar = "A-Z0-9.,;:{([`'\""

nnoremap <silent><C-Left> :<C-u>cal search('\<\<Bar>\%(^\<Bar>[^'.g:camelchar.']\@<=\)['.g:camelchar.']\<Bar>['.g:camelchar.']\ze\%([^'.g:camelchar.']\&\>\@!\)\<Bar>\%^','bW')<CR>

nnoremap <silent><C-Right> :<C-u>cal search('\<\<Bar>\%(^\<Bar>[^'.g:camelchar.']\@<=\)['.g:camelchar.']\<Bar>['.g:camelchar.']\ze\%([^'.g:camelchar.']\&\>\@!\)\<Bar>\%$','W')<CR>

inoremap <silent><C-Left> <C-o>:cal search('\<\<Bar>\%(^\<Bar>[^'.g:camelchar.']\@<=\)['.g:camelchar.']\<Bar>['.g:camelchar.']\ze\%([^'.g:camelchar.']\&\>\@!\)\<Bar>\%^','bW')<CR>

inoremap <silent><C-Right> <C-o>:cal search('\<\<Bar>\%(^\<Bar>[^'.g:camelchar.']\@<=\)['.g:camelchar.']\<Bar>['.g:camelchar.']\ze\%([^'.g:camelchar.']\&\>\@!\)\<Bar>\%$','W')<CR>

Comments

I believe that the pattern should start with \C, to force case sensitivity, as so: 

nnoremap <silent><C-Left> :<C-u>cal search('\C\<\<Bar>\%(^\<Bar>[^'.g:camelchar.']\@<=\)['.g:camelchar.']\<Bar>['.g:camelchar.']\ze\%([^'.g:camelchar.']\&\>\@!\)\<Bar>\%^','bW')<CR>

My addition for visual mode (you need to enter visual mode first) 

vnoremap <silent><C-Right> <Esc>`>:<C-U>cal search('\C\<\<Bar>\%(^\<Bar>[^'.g:camelchar.']\@<=\)['.g:camelchar.']\<Bar>['.g:camelchar.']\ze\%([^'.g:camelchar.']\&\>\@!\)\<Bar>\%$','W')<CR>v`<o
