Inserting an empty lineEdit

With the following map, you can press Enter in normal mode to insert an empty line.

:nmap <CR> _i<Enter><Esc>

Here is an alternative:

" Enter a blank line below/above cursor in Normal mode.
" The o command will continue comments in a program.
nmap ,o o<Esc>k
nmap ,O O<Esc>j

Inserting a spaceEdit

If you manually align text (declarations, ascii tables, trailing comments), you'll find this simple mapping useful.

In normal mode, it inserts a space to push the rest of the line to the right, while leaving the cursor in the same position.

:nnoremap <Space> i<Space><Esc>

For example, suppose we want foo to be aligned with bar:

int   foo;  // ...
double    bar;  // ...

Move the cursor just after 'int'. Press Space until 'foo' is aligned with 'bar'.
