I would highly suggest to *never* use nmap. When you need mappings use
nnoremap so that other mappings do not interfere.

Specifically if you are using vim-latex-suite it has loads of annoying
insert-mode mappings which I was always disabling.

… and move cursor one character back (BTW, this <Esc> is not present above).

… before the current character

When creating mappings try to type them. You must not use `P` if you
need to paste *after* curly brace, `P` pastes *before* the cursor and
<Esc> moves cursor just at the curly brace. You need `p` here. Though
better use `<C-r>`, specifically in your case it would be `<C-r>"`.
Christian Brabandt has another example.
