How do I append text at the end of lines with different lengths using visual block?

Explanation

When lines have varying lengths, a normal visual block selection stops at the shortest line. Using $ in visual block mode extends the selection to the end of every line regardless of length, allowing you to append text at the true end of each line.

How it works

• <C-v> — enter visual block mode
• j (repeated) — extend selection down
• $ — extend selection to end of each line (ragged right edge)
• A — append after the selection on every line
• Type your text, then <Esc> — applies to all lines

Example

Before:
foo
foobar
foo baz quux

After (appending ';'):
foo;
foobar;
foo baz quux;

Tips

• Without $, block selection is rectangular and won't reach the end of longer lines
• This is ideal for adding semicolons, commas, or closing brackets to lines of varying length
• Use I instead of A to insert at the beginning of the block selection
• Combine with gv to reselect and apply another transformation
