: R! Command Import command execution results to cursor location, such as: R!cat/etc/redhat-release

2. Define shortcut keys

: Map ^p i#<esc> Note ^p is at the same time holding down ctrl+v+p settings, P is to set the shortcut key i#<esc> means to insert # at the beginning of the line and back to command mode, you can also press CTRL + V, and then press Ctrl+p to set, when using shortcut keys

Can be used with ctrl+p.

3, continuous Comment line

: N1,n3s/^/#/g N1,n3 represents the first and 3rd lines, ^ represents the beginning of the line, meaning to add the beginning of 1-3 lines #

: AB mymail [email protected] Replace

The above once the server restarts, all of the set of fast keys will be invalidated, we can write it into the configuration file, in the current user's home directory to create a new VIMRC, as the root user example

In VIM/ROOT/.VIMRC

Set Nu
Map ^p i#<esc>
