unimpaired is yet another useful Vim plugin by Tim Pope. It provides convenient key sequences for common operations in Vim.

It can be installed for Pathogen by cloning its Github repository.

A couple of the mappings that I find most useful is [b and ]b to switch forward and backward between buffers and ]space to add a new line without going into Insert mode. These and many more of such key sequences are available through unimpaired, have a look!

Tried with: Vim 7.3
