(used for long range while
normal node for local range,

Specify a range of lines by address
`:2,5p`
`:.,$p` // . current line
Specify a range of lines by visual selection
`2G` + `<S-v>G` + `:` +
`s/vim/emacs`
Specify a Range of lines by Patterns
:/<html>/, /<\/html>p
Specify a Range of lines by Offset
:/<html>/+1, /<\/html>-1p
T29: copy `:t`, or move `:m` lines
Copy lines with `:t` command
`:6copy.` // copy line 6 to current line
`:6t.` // `t` is the same as `copy`
// this is more convenient than normal mode `6G` + `yy` + `1G` + `p`
Move lines with `:m` command
`<S-v>3j` + `:m$` // select 3 line and move the end

T35: run commands in the shell
`:!ls` run ls bash command in vim
`!` is named "bang"
Note `:!ls` diffs `:ls`, which
run vim built-in ls command to display buffer list
`:shell` enter shell from vim
`:exit` exit shell back to vim
use content of buffer as stdin or stdout
`/`: search pattern
an expression
Files
File (in disk)
`:write`, `:update`, `:saveas`
Buffer (in-memory mapping of files in disk)
Consistent with file when file first loaded to buffer;
when buffer is changed the two diverge;
When buffer is saved to file, the two are consistent.
T37: track open files with buffer list
`:ls`
`:[b`, `:]b`, `:[B`, `:]B`
`:N1bd`, `:N1,N2bd`
T38: group buffers into a collection
