Visual increment

Vim's increment (CTRL-A) can be used on a visual selection for more control. One could, for example, only increment the first digit in a series of numbers.

To create an incrementing sequence, select multiple lines and use g CTRL-A. This can also be used with a count. Use g CTRL-A to turn:

0
0
0
0
0

into:

1
2
3
4
5

or 10g CTRL-A to turn it into:

10
20
30
40
50

Source:

• :h CTRL-A

• :h v_g_CTRL-A
