生成序列生成自增序列 generate number sequence

Go to line #4, use Ctrl-v to blockwise select the first character, go down 4 lines, press Shift i, enter 0  (this is 0, followed by Space) and Esc to exit insert mode.

Now use gv to re-select the previously selected area. Press g Ctrl-a to create a sequence.

I start with a 0 here, so I can re-select by gv. If you start with a 1, you need to re-select by hand while omitting the first 1.

Use 2g Ctrl-a to use a step count of 2.

insert tab 插入tab

While in insert mode or command mode (the : prompt at the bottom of the editor), type CTRL + V then TAB.

Using CTRL + V signals Vim that it should take the next character literally. Even in insert mode.

UPDATE:

As noted by Herbert Sitz, if gVim is in Windows mode (default), you must use CRTL + Q in place of CTRL + V.

yank cycle 循环调用剪贴板内容

可以通过调用delete的default register实现
