Vim-Multi-File Operations

Multi-File Operations
Vim supports multi-file operations, including two methods:

1. open multiple files at the same time. In normal mode, enter:

: E → open a new file. The current file must be saved.
: Buffers → list all open files in current vim.
: Ls → equivalent to: buffers, which lists all opened files in current vim.
: BN → switch to the next file.
: BP → switch to the previous file.
: BD → close the file.
: B (Num) → switch to the file whose serial number is num. The serial number is obtained by the LS command.
GF → open the file name at the cursor.

2. Split the screen. In normal mode, enter:

: Vsplit → create a vertical split screen. You can directly enter the file name you want to edit, for example, vspilt filename.txt.
: Split → create a horizontal split screen.
