How to define shortcuts in VIM

Previous blog 《Copy content in VIM to system clipboardThis section describes how to copy the content in VIM to the system clipboard. It can be seen that a copy requires many keys, so I want to define a shortcut key to simplify the operation. The process is very simple. For example, if I want to set the shortcut key for copying the full text to Ca (meaning copy all), the process is as follows:

1. test whether the CA is in use. Enter CA in normal mode to check whether there is any response. If not, the Ca is not in use.

2 edit ~ /. Vimrc file, add

Map ca {ggvg "+ y}

3. Open a file and press CA in normal mode. The message "Copied ** line" is displayed.

In the insert mode, if you want to switch to normal mode, press the ESC key. Because the distance is too long and the operation is inconvenient, a keyboard ing is usually performed.

Edit ~ /. Vimrc file, add

Imap jj <ESC>

In this way, in the insert mode, it is too convenient to press JJ twice consecutively, not only does not input two j s, but also switches to the normal mode!
