How do I append text at the end of multiple lines using visual block?

Explanation

Combining visual block mode with $ and A lets you append text at the end of multiple lines, even when the lines have different lengths.

How it works

1. Press <C-v> to enter block mode
2. Select lines with j
3. Press $ to extend to end of each line
4. Press A to append
5. Type text and press <Esc>

Example

alpha
bravo
charlie

Select all lines with <C-v>2j$, press A, type ;, press <Esc>:

alpha;
bravo;
charlie;

Tips

• Without $, the block only extends to the shortest line length
• $ makes the block extend to the end of each line individually
• This is the standard way to add semicolons or commas to multiple lines
• Also works for adding trailing comments
