For those of you who require a way of capitalizing (or toggling the case) of words in either insert or normal mode but want the cursor to stay put where it currently is, you're in luck.
The mappings below work in such a way where the word being capitalized is the word where one of its alphabets is being "touched" by the cursor.
When it is in normal mode, the cursor only touches the alphabet underneath it (i.e. alphabet under flashing cursor block).
When it is in insert mode, the cursor touches the alphabet beside it. A few examples below (assume pipe character as cursor):
foo| bar– "foo" gets capitalized
foo |bar– "bar" gets capitalized
foo b|ar– "bar" gets capitalized
foo bar | more– no word gets capitalized
Cursor stays where it is after capitalization, in its current mode.
"Place in vimrc file "<F7> for word case toggle & <F8> for word capitalization "Normal mode mappings: nmap <F7> mzg~iw`z nmap <F8> mzgUiw`z "Insert mode mappings: imap <F7> _<Esc>mza<C-Right><Esc>bg~iw`zi<Del> imap <F8> _<Esc>mza<C-Right><Esc>bgUiw`zi<Del>
Type "~" for togglecase, "U" for uppercase, "u" for lowercase.
These ones seem to work better than the last. Updated insert mode mappings:
imap <F8> _<Esc>mzwbg~iw`zi<Del> imap <S-F8> _<Esc>mzwbgUiw`zi<Del>
The last mappings broke for words at the end of the file.
imap <F8> _<Esc>mzi<S-Right><C-o>b<C-o>g~iw<C-o>`z<Del> imap <S-F8> _<Esc>mzi<S-Right><C-o>b<C-o>gUiw<C-o>`z<Del>
